  • SR-1016 #selector broken for no-argument initializers and functions

Issue Description:

Currently, using #selector requires parenthesis when referencing functions and methods with arguments, but disallows parentheses when referencing those without arguments.

I recommend that a set of empty parentheses be required for selecting functions and methods which do not have arguments as to be similar to the syntax of defining a function or method without arguments.

The reason it's the way it is is because () would normally call the method, but you're not the first to suggest that in #selector that distinction isn't useful.
