Subject: Feature request: enhanced break
Optional integer constant after "break" specifies number of enclosing
loops to break. `break 1` means the same as `break` without a number.
Example: find an item in a table of lists, with shortcut exit from a list.
for k,a in pairs(t) do
for n,b in ipairs(a) do
if futile(b) then break end
if found(b) then row,col = k,n; break 2; end
end
end
Seems a bit errorprone to me. Doing maintenance, adding a level due to another loop wrapping some existing piece of code. Now the levels I have for break no longer match...
I'd go for the already mentioned `goto` approach, as the more transparent solution.
