Lua 5.2 Reference Manual, §3.3.4:

"For syntactical reasons, labels in Lua are considered statements too ...
The return statement can only be written as the last statement of a
block. If it is really necessary to return in the middle of a block,
then an explicit inner block can be used, as in the idiom do return
end, because now return is the last statement in its (inner) block. "
