[Numpy-discussion] Small fix to Numexpr getType()

[Ivan Vilata i Balaguer]

Hi all,

According to Travis' advice in a prevoius thread (see
http://www.mail-archive.com/numpy-discussion%40scipy.org/msg00442.html),
I have modified the ``compiler.getType()`` function in Numexpr so that
it uses the ``dtype.kind`` attribute instead of ``issubclass()``.  The
patch is attached.

By the way, what is the proper casing of "Numexpr"? :)
