>I kind of like the idea that since one can use when clauses in a for, given doesn't alias. If you want aliases, write for; otherwise, write given.

Yeah sounds like perfect orthogonal design. Though one has to keep in mind that leaving the block demands different statements. 

use feature qw(switch);
 
given (1) {
  print;
  break;
  print
}
 
for (1) {
  print;
  last;
  print
}

UPDATE:

confusingly this works well:

$\="\n";
 
for ("012") {
  if   (/0/) {print "0 matched"};   # prints 0
  when (/1/) {print "1 matched"};   # prints 1
  when (/2/) {print "2 matched"};   # nix
  if   (/3/) {print "3 matched"};   # nada
}

but the perlsyn says Every "when" block is implicitly ended with a "break".

Consequently "break" should also leave loop-blocks, or the documentation should be updated.

IMHO break is needless and should be abandoned in favor of last. (which linguistically still makes sense)
