You need to add tests for nested labels, so r- for that, but also i don't believe that you're right to make L1: while(1) { L1: while(1) {}} an error so i want to know what justifies that decision.

You have just made
L1: while(...) { L1:  while (...) { ... } }

A syntax error, which it never was before.  What portion of the spec says that this is an error?
