We want to run Lua on an machine without floating-point-unit and basically only need integer numbers. How much effort is it to switch the number type to long instead of double? Is it possible to have

You don't need that second colon. Since do, break and end are keywords, do:foo, break:foo and end:foo can't be ambiguous. Spaces around the first colon could be optional. Some might argue that they i

What if the __len value of the metatable of a table was used as the value of the length and tables have a default metatable that causes `t.n` to trigger __len, essentially making it the same as `#t`?

I originally implemented it for the 5.2-rc and had to modify it slightly for 5.1. It got a little larger as 5.1 has no readhexaesc. As a bonus you get hex-escapes, too. Here you go: diff --git a/src/
