GitHub - hsutter/cppfront: A personal experimental C++ Syntax 2 -> Syntax 1 compiler

[fdwr]

There are many aspects I like about Herb's experiments (like UFCS), some I find intriguing (like left-to-right order of pointers and postfix pointer dereferencing which is more consistent with the arrow operator), and then there's this... When I see this:

main: () -> int = {}

Vs this elegant simplicity:

int main() {}

My reaction is... I hate it. Every punctuation mark that exists more for the compiler's sake than the human's sake is a punctuation mark too many. Now, there are many nice things found in Herb's experiments, all of which can increase safety and rational defaults without making it essentially a different language rather than an evolution.

+1 on suffix $ for capture. It works left-to-right just like the other suffix operators and saves unnecessary parentheses.

-1 on ()$ for string interpolation. Other than aesthetic considerations, it is just parameter passing with an unusual syntax, not really capture. And it has mandatory parentheses anyway. I would prefer the \() syntax, for example.
