It would be cool if you could use break with do ... end for some sort of
"safe goto"
Example:
do
break
local x = "you'll never see me"
print(x)
end
print("something")
Would print "something"
In 5.2+ we have this:
goto x
local x = ""
::x::
print("something")
But it errors instead of doing the scoping stuff you can do with do ... end
(This is probably not something for lua 5 but for lua 6 if/when we get it...
it would probably be less harmful to change goto so that it does an implicit
do ... end scoping thingy)
repeat
-- statements here
break
-- rest of statements skipped
until false
