Why did you write it with two structs though? You could do #define defer(body) DeferHolder COMMON_CAT(_defer_instance, __LINE__) {([&]()->void body)};
and call it as defer({
function body here;
});
Which looks much nicer. The preprocessor treats balanced curlies as one single token regardless of how many lines it spans, precisely to enable this usage. |
