What might happen with this is that if you concatenate a bunch of .js files
that use this pattern, they might end redefining the same label (which would be
an error, I guess). Wrapping it all in another block would solve that?
{
block: {
if (true) {
break block;
}
}
}
But then... I'm not sure this is any better than an IIFE!
You can also use a less naive concatenator. Labels seem to be very
static parts of a JS program. It sounds doable to find and rewrite them.
Given what people have been doing with esprima recently [1], I have the
impression it would be even easy (?)
