You can't, but you can move the same code inside a function and call that
instead.

In Lua 5.0, you can get the "top level function": it's left on the top of
the stack by lua_load in C and returned by loadfile or loadstring in Lua.

'continue' keyword

Hi all,

I was putting together a little powerpoint slide (argh! yuck!) to give an
overview of LUA to a few colleagues, and I was writing a comment about
'break' being here to break out of loops, and I thought that there is no
'continue' keyword. Is this because nobody ever needed it, or is there some
other reason ? It could be useful though...

Cheers,

Benoit.

I can't even begin to say how useful this would be.  Many of my loops
have great big nested if-else blocks because I can't force start the
next pass of the loop (through 'continue')...

A tolua for Lua 5.0 will be available by the time Lua 5.0 final is released,
which should still be in 2002.

What is the expected timing of LuaSQL and LuaSocket
being converted to Lua 5.0?

I believe this question has been raised already.

I tried to search the archive using the Web interface, but the
<http://lua-users.org/lists/lua-l/> URL seems broken, I got a directory
listing (with only the 2002-05 folder, containing only msg00159.html)
instead of the search form. 

Searching 'continue' in the old (January) archive I have on my hard disk,
I see the topic was first mentioned on 30 Oct 1997! Message-Id:
<199710300318.JAA05107 <at> odusv.oduurl.ru> A lot of people stated they miss
continue (and break, which wasn't in the language at the time). 

Another request was in 15 Sep 2000 Message-ID:
<ce.aa17026.26f3498f <at> aol.com>, and I think it was asked recently too. 

Now, I can't remember the official answer
