Perhaps having to do with this:

> _,_,a= string.find( "100", "(%d+)" )
> print(type(a))

I've always wanted a "(%d+)" caption to give me a number, not a string.

Motivation for the patch: I don't like automatic casting; it hides bugs. I also think it rarely[1] helps users, and if it does (e.g. in a config
file), then you can do the auto-casting yourself (e.g. read a config
file, and call "to<type>(v)" on each value you read).

[1]For example, print is one function I've left alone. This is an
example of the fine line in Lua between auto-casting and intentionally
calling a tostring method.

Nice to know that I'm not the only one who dislikes the implicit
coercion-- however I don't think the line you mention is that fine. The print function is intended for debugging (e.g. dumping a given object),
and it makes sense to call tostring() on its arguments.  That's a
documented behavior performed explicitly by the function, and very
different from the implicit coercion taking place in an expression like
(5 + "5").

To resolve Mark's issue with string.format in another post, I think the
existing %s should run tostring() on its argument.  There's no want or
need for a strict string format type.
