What's the rationale of keeping the requirement that the
condition of if/for/while must be wrapped with a parenthesis
(other than keeping parser simple)? Modern languages have
already dropped this requirement (i.e. Rust, Nim) and I don't
see any reason not to do so.
There is this case that requires parens:
if a && b c;
Is there a missing && or not ? It seems obvious for a human but
compiler parsers are "apparatchiks", i.e rules are rules. That
being said this would work by allowing parens for
disambiguation.
Same thing as the following"
return a && b;
I'm not saying to drop parens completely, I'm saying why is it
not optional. D seems to have no problem with x.to!string or
std.lines
