Align comparison operators (#1330)

Browse Source 
In functional.h, the comparison operators for equal_to and not_equal_to
mismatch between the actual comparison execution and the type inference
for the return type. This change adjusts it by using the same operator==()
in the return type inference as used in the comparison execution.
