[cffi-devel] why is null-pointer a function?

[Tamas K Papp]

Hi,

I would like to ask why null-pointer is a function, not a variable...
One reason is just curiosity, the other is that I want to know if it
is safe to save the result of (null-pointer) in a variable and use it
from then on (less parens, fewer function calls).

Thanks

Tamas
