Fully Vectorized

This is obviously a very difficult problem that relies on a few parts being successful.

No:	Dependency Changes	Strict Typing	Implementation	OS	Performance Gains	Implementation Difficulty
1	None	Possible	CPython, PyPy	Windows, Ubuntu, MacOS	Insignificant	Easy
2	Numpy	Partial	CPython	Windows, Ubuntu, MacOS	Significant	Difficult
3	Scipy	Not Possible	Cpython	Windows, Ubuntu, MacOS	Significant	Normal
4	Conditional Numpy	Partial	CPyhton, PyPy	Windows, Ubuntu, MacOS	Significant	Very Difficult

Option 4 is ideal for best compatibility and performance but is a huge undertaking at the end of which strict typing may still end up being not possible.

Regardless of which option is being pursued, these tasks need to be completed first:

• Full Strict Typing  #85
• Automatic Test Generation and Parameterization #86

I've decided to not go ahead with this for v5.0.0. Platform support is more important that raw performance.
