Hi,

I have an idea of making parenthesis optional for functions having no
parameters. i.e

def greet: # note the missing parenthesis
    print('hello')

The less awkward characters we have, the more readable our code will be
(Beautiful is better then ugly). Some people argued that function
definition with parenthesis seems to them natural. But actually it seems to
us natural, because we have been used to it a-lot. IMHO parenthesisless
functions definitions are natural and readable.

In Python we have already adopted this. i.e parenthesis are optional in
`if` statements, in class definition, in tuple etc

if x == 1: # parenthesis are optional here
    pass

class Greet: # now we don't explicitly inherit from `object`
    pass

Tuple = 1, 2, 3 # parenthesis are optional here too

Please, give your opinion.

Thanks, Adnan Khan
