There's a very common idiom where in order to report line

function, you pass __FILE__ and __LINE__ as default parameters:

void foo(string file = __FILE__, size_t line = __LINE__)(string
msg);
Wouldn't this solve it?
No, because a) then you're completely pointlessly making a foo
for every line it's called in, b) you're not future compatible
with, say, call column, and c) you get exactly the same problem
with template value parameters, ie. foo!"some ct argument".
