This looks really cool. However, it does seem to break scalar
operation:
a = 3.
b = 4.
expr = numexpr("2*a+3*b",[('a',float),('b'.float)])
expr.run(a,b)
Out[41]: array(-7.1680117685147315e-39)
I havn't used numexpr before, so I could be doing something silly
(although I did verify that the above works on r1986).
