Hi all, I'm new to this list but I was writing some notes about paren-free calls this morning and thought they might be relevant.
The trouble with paren-free calls, as implemented in CoffeeScript and others: - they overload the space character, making it mean something different in only a small fraction of cases. - they break down whenever calls are nested or part of another expression (requiring a fall-back to explicit parentheses). - they also make certain other things impossible to write, like named function declarations (blah -> becomes blah(->)). The first point is major, in my opinion. If the goal is to have an argument list opener that doesn't require an explicit close, then some other character(s) would be a better solution than forcing people to read possible double-meanings into every space they see. U+0020 is consistently high up in the top 5 most-repeated characters in a JavaScript program, so overloading its meaning for a minor cosmetic effect is not justifiable IMO. And the writability improvement of making list closure optional can be achieved by other means, if it's considered that important.
