Title: learn_type() for all libraries, other misc changes

Here's the implementation of learn_type() for all the other libraries, as well as some miscellaneous changes:
- Clean up warnings/notices.
- Check for unknown arguments for all types in all libraries.
- Add //str length to all libraries (now redundant with your own addition of same).
- Throw explicit error objects (partially redundant).
- Add more tests.
- Minor corrections to the website.
