Re: Does Lua have a Roadmap?

(1) '5' + 5 gives you an 10.0 in the interactive console. Isn't this a weakly typed language behavior?

(2) '5' + 5 > 10.0, string plus integer equals float. If an error was throw here, it would be easier to understand than the given behavior.

Two things:

(1) Lua is already strongly typed. It just has a very small list of
recognized types, and one of those types is "table".

(2) Stronger typing than this would not simplify the language
whatsoever. It would require a mechanism by which user-defined types
can be added as well as mechanisms by which these types can be
identified, manipulated, and instantiated. You could reasonably argue
that it might make the language more ROBUST, but it would not by any
means be SIMPLER.
