Issue:
IPython/utils/py3compat.py unused `with_metaclass` function. 
The function `with_metaclass` seem to be unused; 

we should :  check if it is used, if not remove the function .

Issue:
IPythonConsoleLexer fails with python2 and pygments 2.5
As of pygments 2.5, `PythonLexer` [now](https://pygments.org/docs/changelog/) is an alias for `Python3Lexer`. iPython still uses `PythonLexer` for the python2 case:

https://github.com/ipython/ipython/blob/a6082c6ff799e4ec30ad24afbfc5f1550185934d/IPython/lib/lexers.py#L79

It should explicitly use `Python2Lexer` instead.


Discussion:
Please submit a pull request to fix that. Thanks!

Issue:
ipython 5 won't install on python 2.7
The latest release (2.6.x) of the pygments dependency is python >=3.5 only.

As the pygment version is unbounded by ipython, this breaks the installation of ipython 5.9.0 on python 2.7 (this is last version supporting python 2).

If you wish to maintain the support of ipython on python 2.7, then you need to pin pygments to <2.6.

Issue:
Pyside2 5.15 seems to break --gui qt on mac
Just a heads up, I think pyside2 5.15.0 may be breaking IPython GUI event loop integration.

```
conda create -n test python=3.8
conda activate test
pip install ipython pyside2==5.15
ipython --gui qt
# cannot type anything into the interpreter!

pip install pyside==5.14.2
ipython --gui qt
# works again
```

tested on two different macs: 10.15.4 and 10.13.6


Discussion:
on further examination, this may be an issue upstream of IPython, either in `prompt_toolkit`'s`InputHookSelector` or in asyncio ...   What I can say is that the event loop is stopping somehow.  After starting the gui loop with either `ipython --gui qt` or the `%gui qt` magic, the inputhook at `terminal.pt_inputhooks.qt.inputhook` gets called only a couple times before the prompt becomes unresponsive to keystrokes (and `inputhook` is no longer called).  Since[ the main update in 5.15 is threading related](https://www.qt.io/blog/qt-for-python-5.15.0-is-out), seems like something is not playing well with asyncio

Issue:
pexpect version requirement
Hello.

I found that when I install ipython for python3.7 with `pexpect` of version `4.2.1`, ipython crashed with an syntax error, it is because `pexpect` of this version named an parameter with `async`, which becomes a reverved keyword since python3.7. I sugggest that `pexpect` version must be specified to be compatible with python3.7 or above.

Thanks.

Issue:
Documentation formatting is inconsistent
There are some docstrings that are not consistently formatted and sometimes result in a supposedly unexpected format in the ipython.readthedocs.io

An example:

https://ipython.readthedocs.io/en/stable/interactive/magics.html#magic-env

    %env
    -----
    
    Get, set, or list environment variables.
        
    Usage:
        
    %env: lists all environment variables/values %env var: get value for var %env var val: set
    value for var %env var=val: set value for var %env var=$val: set value for var, using python 
    expansion if possible

For this case it would probably be best to use [field lists](https://www.sphinx-doc.org/en/master/usage/restructuredtext/basics.html#field-lists).

It might pay off to do a systematic review of the docstring formatting.

Thanks for reporting this; sorry for a late response. Looks like someone forgot to RST-ize the docstring. PRs welcome.
Can I try to work on this issue?

```

```

## System info

Issue:
%rerun prints a misleading error when 0 lines are requested
## Steps to reproduce

* Execute `%rerun -l 0`

## Expected result
Nothing rerun, nothing printed 

## Actual result
Nothing rerun, but the following is printed
```
No lines in history match specification
```

## Comment
This error message is relevant to another part of `%rerun`'s functionality, namely, rerunning based on search with `-g <query>`, but is confusing here.

Issue:
%cpaste doc error: Magics ARE supported
`%cpaste?` claims "IPython statements (magics, shell escapes) are not supported (yet)."  But at least magics apparently are!  



Discussion:
Also, for some reason `%cpaste` docs aren't rendered in RTD (or at least I cannot find them).
