std.path is supposed to work on strings, it doesn't touch std.file at all. Why
can't it run at compile time?

Most of Phobos is written in D, and D distributions contain full source code,
so in similar cases you just need to take a look at the sources of Phobos and
do some experiments to locate the problem. It seems your problem is caused by a
CTFE bug, I will file it in bugzilla:


int foo(int x, int y, int[] more...) {
    return 0;
}
enum r = foo(0, 0);
void main() {}


Bye,

Yeah. I was in the middle of something so I was too lazy to go figure
it out on my own, hence I posted it here. :)

Thanks!
