Re^4: strong typing

Perl's type system has no concept of "integer", "boolean", etc.--it only knows about scalars...

But that isn't entirely true:

print 5 == "foo";
Argument "foo" isn't numeric in numeric eq (==)

The fact that these types are checked/enforced at run time rather than compile time doesn't mean they aren't types. It's called dynamic typing.

Those aren't types in Perl. Those are values.	[reply]

Huh? You're saying `numeric` is a value? No. It's a type. Values have types. It's the type of "foo" that perl is complaining about, not its value.	[reply] [d/l]

Containers have types in Perl. Values don't. That's how (I say) Perl's type system works. (Okay, that's not entirely true, but if you need gory details, look in sv.h and Devel::Peek. My point is that Perl doesn't expose the types of values to users.)	[reply]
