• Deprecate map.foo() in favor of map.foo
• Deprecate mod.foo in favor of mod.foo()
• Change the AST so remote calls (A.b, a.b, etc) without parens has nil third element. Once we do so, remove :no_parens metadata usage throughout the codebase (perhaps behind the --future flag)

PS: originally this issue was about deprecating all nullary remote calls without parens, but it has been restricted since then. See this comment for more info.
