[gameprogrammer] More scripting engines

Just had an idea. (Probably not a new one, though I haven't seen it
before myself.) I was going to have these "multilevel" break
statements, but I don't like the "break <n>" form, where you have to
explicitly specify the number of levels you want to jump. (Wrap a
loop in an extra loop forgetting to adjust your breaks, and weird
things start happening...)
So, if figured I'd name the nesting levels instead, something like
this:
while something
outmost
{
while something_else
{
check some, stuff;
if all_done
break outmost;
if nope
break;
}
}
where 'outmost' {...} would be a named scope. (A {...} delimited block
is a statement, so I can just add NAME '{' block '}' to that grammar
rule grammar.)
Another syntax variant:
while something
{
nestlevel outmost;
while something_else
{
check some, stuff;
if all_done
break outmost;
if nope
break;
}
}
This was my first thought, but I don't quite like it. I'm not totally
happy with NAME '{' block '}' either though.
If anyone has some interesting ideas for the syntax, I'm all ears. :-)
