Yes, that's right.

So do we, but not necessarily for Lua.

This is our point: being a nice language feature is not a good enough reason
for adding it to Lua, specially an obscure feature like break labels.

We haven't seen any really good uses of labels, except the abstract "break
from an inner loop around an outer loop", which of course can be done with
functions.

So, does anyone have really good, concrete uses of break labels?
