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.
