4448 – labeled break doesn't work in CTFE

string CTFE(string s) {
 int i, j;
 L1: for(i = 0; i < s.length; i++)
 switch(s[i]) {
 case ' ', '\n', '\r', '\t':
 continue;
 default: break L1;
 }
 L2: for(j = s.length; j > i; j--)
 switch(s[j-1]) {
 case ' ', '\n', '\r', '\t':
 continue;
 default: break L2;
 }
 return s[i..j];
}
import std.stdio;
pragma(msg, CTFE(" hello world!\n"));
void main(){ writef("'%s'\n", CTFE(" hello world!\n")); }
the function works at runtime but fails under CTFE. There may be a few cases where labeled break may be hard to deal with but this one shouldn't cause problems.
