If I understand this right, then this would become legal too:
x = if cond(a): return b
return would always be a syntax error outside of a function.
So what value is assigned to x when cond(a) is True, what value when it is False?
x = if False: 1 # evaluates to None x = if True: 1 # evalutates to True x = if True: return 1 # syntax error: return outside of function
def foo(): x = if True: return 1 # exits the enclosing function. value of if-expression is moot as it's never reached.
What value does return return? The thing is that return does definitively not return anything, but as a statement, it can be placed everywhere in a block.
Not that it matters, but return always returns something, either a user-specified value or None.
