Man, i must admit i really like this, and your code will look so much
cleaner.
It has benefits - code does look better. It has also significant cons - it is
ambiguous.
For instance:
a = b
Is b a variable or a method called without parameter?
Hello Emanuel,
Again, who so ever names a method with such a non-descriptive name
will get whats coming to him. And if you did for some reason use such
a cryptic name as "b", do yourself (and everyone else) a favor and
follow it with "()" to denote the method call. Remember when something
is optional that means you have an option to use it OR not use it.
I believe his point is that it is ambiguous to the compiler, not humans reading
the code. Python functions and methods are first class objects. They can be
passed around. If they were auto-called, then you could not do this.
