Summary

  1. RULE: while doesn't assign any variables (like foreach ) it's a boolean check alike if(CONDITION) { DO LOOP }
  2. Some operations assign automatically to some vars (side-effect) and return true on success. E.g. regexes setting $1 etc can be combined with a boolean check.
  3. Some like <FH> do this only inside while(<FH>) context for exceptinal DWIM
