Err, umm, you mean that first line of the second paragraph
in the docstring? *blush*

My proposal is to replace that code with a table mapping
the type name to the uppercase/lowercase/capitalized forms,
thus eliminating the (small) amount of time needed to
It makes adding new types slightly more difficult.
I know it's a tradeoff. In this case it's somewhat like the
proverbial New Jersey approach vs. the MIT one. The code that's
there is the right way to solve the problem in the general case, but
solving the specific problem can be punted, and as a result the code
is (slightly) faster. Other parts of the code are like that, which
is why I pointed out so many examples.
Startup performance has not been a numpy concern. It a concern for
me, and it has been (for other packages) a concern for some of my
