You can already do compact conditional returns with the current syntax:
def foo(a, b):
return (a != b or None) and a * b
or even:
foo = (lambda a, b: (a != b or None) and a * b)
both return:
foo(2, 5) # 10
foo(1, 1) # None
... but clarity would be better.
That can be written more clearly:
def foo(a, b):
return a * b if a != b else None

Only around 10% of "if" expressions have "else None" part. It is not
enough to justify a new syntax (even if ignore other objections).
