Naming: Remove all underscores to matter what?

[ScottPJones]

@StefanKarpinski

Use underscores except when there’s a strong legacy reason for not doing so. However, this is a pretty subjective judgment call, and leaves the language with a wildly inconsistent experience where – much like English spelling – you have to know the provenance of a name in order to guess how to spell it.

Another option would be to:

1. First see if the functionality can be put in an easy to use API with using multiple dispatch and/or keyword arguments, without performance penalty. (The changes in master seem to be shaping up nicely to help out with that)
2. Otherwise use underscores to provide longer, readable names (sparse_ones instead of spones, for example). (Hopefully, in most cases No. 1 could make this rarely necessary).
3. Create packages that provide legacy names (Matlabisms such as cumsum, cumprod etc. come to mind), so that legacy names don’t pollute the Base namespace. That would help resolve the problem you identified about the language feeling inconsistent. (It already feels inconsistent, this could improve things).
