/prog/ - n-breaks? — Tinychan BBS

Why can't we just have break accept a number so we can break multiple loops at the same time?


    for( /*...*/ ) {
        do {
            x = f();
            
            switch( x ) {
            case Error;
                break 3; // was that so fucking hard?
            }
        } while( /*...*/ );
    }

Dare say I should use... EXCEPTIONS?!

Its called goto.

break is just a constrained goto

because of undefined behavior

WPLIT? if C or Seeples, use goto. if Java, break to label. I don't know if there's a language that supports breaking out of n loops dynamically, that would require more runtime information (loop returns on stack?)

How about you restrict n-breaks to positive integer literals?

then you can just use labels

I found an answer!!!!!!!

for(float a = 0; a < 2.4; a++) {
  for (float b = 0; b < 99.3; ++b) {
    for (float c = 0; c < 35.16; ++c) {
      for (float d = 0; d < 9.1; ++d) {
        for (float e = 0; e < 28.3; ++e){
          int x = f();
          if (x == false) b = 99999999;
        }
      }
    }
  }
}

This doesn't stop them.
Although I guess it would if you did the same to the other inner loops.

If you're suggesting that unironically, then no that's not a good idea.
