February 27, 2013 optional parens everywhere except last position of function chain. | ||||
---|---|---|---|---|
| ||||
Here's yet another proposal regarding optional parens that makes a single simple rule to resolve ambiguities: A symbol 'foo' that refers to a non-@property-qualified function or function template is rewritten to foo() iff it is followed by a dot ("."). There's probably a better way to rephrase this in terms of AST, but in other words, parens are optional inside a function forwarding chain, but mandatory for the last element of the function chain. When a,b,c are non-property functions: a.b.c(); => a().b().c(); // c is called a.b.c; // c function not called c(); => // c is called c; => // c not called typeof(c) => function type typeof(c()) => return type [1,2].sort.map!cos.array.sort.reduce!max.writeln(); =>[1,2].sort().map!cos().array().sort().reduce!max().writeln(); Advantages: No complex special cases, it is unambiguous for both compiler and user. Please let me know what you think. |

Spontaneously... I hate it. :)
I prefer optional parentheses everywhere.
