Are you talking about the constant values 1e60 and "foo"? If not then =
please don't add a warning (or worse).

I'm sure there is a lot of code which takes user input and uses (int) =
casts to ensure they are dealing with integers.
There is also intval() as an alternative but my guess would be that real =
world code uses 50% (int) and 50% intval() to do this.

This would be a big BC break IMHO.
