1. Tagged loops (was RE: [PATCH] experimental php-like 'break N' to break acrossmultipleloops) (score: 536)

Spaghetti code come from carelessly used unconditionnal jumps (that is the bad goto). I aggree that it can complicate code maintenance, but the (bad) relationship between coders and goto is biased by

We would just have to tag loops and use that tag in break statements. Example: local prefix = "loop" local i=1 local n = 2 while[prefix..1] i<=10 do for[prefix..2] j=1,10 do if foo then break "loop1"

tagged/named loops have been discussed already: http://lua-users.org/lists/lua-l/2005-10/msg00037.html rici's solution, except being a bit intrusive to the language, works well (testing the patch aga

hi listers, i've found myself doing lot of miserable things today, due to inability of lua to simply break out of multiple nested breakable scopes in one statement. finding nothing useful in powerpat

yep. what about goto? thats named scope too :) spaghetti construct will remain spaghetti construct, no matter the circumstances. (named labels, gotos, numbered breaks...). named scopes are easier to

I'm not sure this is needed, but if other people disagree :) then I think the Perl-esque idea of breaking out to a labelled statement is the way to go. The problem with using numeric levels is that r

Unnecessarily complex and hard to understand flow control can be created with conditionals as well as with goto. "Please don't fall into the trap of believing that I am terribly dogmatical about [the

Hi, The attached file contains modified Lua 5 parser and lexer files with added `continue' keyword. In addition, both `break' and `continue' statements may have optional integer argument specifying w

I've another idea how to capture full loop functionality, in a way I've not yet seen in another language. 1) continue as new keyword - better just get over with it, than to overload existing keywords

[1] We may think of break, continue, redo, and break with labels all as a generalization of "break N", slightly generalizing PHP's and especially Idle's "break N" [2,3]: -- begin scope 3 for x=1,10 d

What about "tagged blocks" as an alternative to goto. (similar to Ada exit)? You can use with any command that creates a block - if, while, repeat, for, do or even a function. and with the end to inf
