RE: Patch to remove auto-casting between numbers and strings

It would sometimes be convenient, agreed. But the string may not always fit
as a number. For instance, my programs have to deal with mobile phone IMEI
numbers - 15 digits, and a loss of precision would be a real problem with
those!

You also lose any leading zeros.

Perhaps having to do with this:

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

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