OTOH, that won't work with local variables (it'd only print the variable
names, not the values). Presumably you'd also want to print the
variables too. So perhaps something like this instead:
auto debugPrint(alias fun, A...)(A args) {
writefln("%s(%(%s, %))", __traits(identifier, fun), [args]);
return fun(args);
}
string arg = "hello";
string myCall = debugPrint!someFunction(1, arg);
