I don’t know if “curly braces are ugly” would be enough of a reason for me,
personally, to abuse the language like this :). I’d probably just play with
whitespace:
if (cond){ callback(); return; }
But I think the cleanest brace-free option would certainly be the comma
operator:
if (cond)
return callback(), undefined;
Parentheses might make it clearer:
if (cond)
return (callback(), undefined);
