Hey Mongers! Goggling around, I could not determine whether or not Perl LABELs are subject to the usual lexical scoping rules as are "my" declared variables. I almost always label "for"/"foreach"/"while" etc. blocks so it should be clear where will "next"/"last"/"redo" go. And sometimes the natural name for the loop is the same, e.g., "EMPLOYEE:". So I wonder if I can reuse the same label if it is clearly in a different scope.
Simple tests were successful, but I would like to have a more authoritative answer. The closest I came to finding any reference to the issue is in <http://perldoc.perl.org/perlsyn.html#Goto> "perlsyn" GOTO: The goto <http://perldoc.perl.org/functions/goto.html> -EXPR form expects a label name, whose scope will be resolved dynamically. This allows for computed goto <http://perldoc.perl.org/functions/goto.html> s per FORTRAN, but isn't necessarily recommended if you're optimizing for maintainability: 1. goto <http://perldoc.perl.org/functions/goto.html> (("FOO", "BAR", "GLARCH")[$i]); But although this does suggest a scope for a label, it does not answer IMHO my question beyond doubt. Can anybody elucidate? Regards, Meir
