Sure, we can do all of this with a good old GOTO, after all.

In JavaFX, for example, we have to write:

  for (i in [ 1 .. 100]) println("...");

ie. we have to generate a sequence (kind of array) filled with increasing numbers from 1 
to 100 to iterate on it. I suppose the compiler optimizes that, ie. that the sequence is 
virtual, not taking up memory.
