By fangly:

I think $ENV{PAGER} is too technical. It does not matter what syntax IO::Pager uses to access the environment variable. What's important is that is clear to the user that this is an environment variable. For example in bash, you would get the value of variable using:
```echo $PAGER```
But you are correct, the POD should refer to that variable as PAGER (that's my preference) and not $PAGER. I can understand that $ENV{PAGER} is perlish and would also be well understood by most people.

Regarding Env, it does not cost very much to use it, and it makes the code a bit more readable. I prefer readability... YMMV

So, in the end, it's your call how we refer to the PAGER environment variable in the POD and if we use Env.
