Hi,

I have a program that creates a lot of lambdify-ed functions from
sympy expressions. The problem is sometimes the function turns out to
be the number zero and when I use the lambdify-ed version of that
function the input shape and output shape do not match. In other
words, the function zero returns exactly 1 zero regardless of how many
items were in the input array. This is inconsistent since if the
function is not zero, then the input/output shapes match.

I hope that made sense.

Currently, I have a bit of logic filter out this case, I would like to
avoid that if there is a way.

Thanks in advance.
