A "label" keyword would be great too, but it will break so much code.
Yesterday Xavier Wang brought to mind an alternative.
I'm missing a reaction to that:
"maybe using a local variable scope for goto destination is better
than define a (whatever) label statement."
In my words: Use "local mark" instead of "label mark" or "@mark:"
I must admit that I have not thought about whether that is
What are thepros and cons?
How would that work with jumping forward?
I must admit that.... :-)
OK, maybe I've missed the whole discussion.
a) Is this problem avoided by "label mark"?
(=> Is repeating a label in the same scope considered as an error?)
b) Is the following rule a bad idea?: "goto mark" jumps to the first definition reachable in scope.
(=> Do not use backward definitions, if you want to jump forward)
