[SciPy-dev] [pymachine] moving code outside the sandbox into scikits ?

Hi, I'm going to throw in my contrary 2 cents and say that I prefer learning
or learn.  The reasons are:
- they are shorter, and therefore easier to type
- they are shorter, and thus produce a smaller desire to abbreviate with
aliases (import x as y).  I think that's good because it reduces the number
of names/conventions that must be defined/remembered as referring to the
same thing.
- they are real words (unlike machlearn), and therefore easier to remember
and type
- adding the word machine seems redundant (I do realize that "machine
learning" is the proper name for the field), since it is software we are
talking about... I guess the only confusion that could arise is that a
newcomer might think it was a package for educating humans about scikits.

Anyway, that's all I have to say on the subject.
