In Python, of course, & is a bitwise AND, logical and being the literal
word "and". & has lower operator priority than <, but "and" has a
I think the real problem is that "and" doesn't work on numarray bool
arrays in an element-wise fashion as I expected; perhaps it should?
Otherwise constructs like
v = A>10 and A<15
have to be written as
v1=A>10; v2=A<15; v=v1&v2
v = (A>10) & (A<15)
