Perl doesn't really have data types in the sense that C or Java does.

C++ has run time vtables and I think Perl has an equivalent concept for OO. So in that sense it is dynamic (can figure out what exact code to execute for a method call at run time - enables polymorphism among other things.

In Perl you can actually write a program "on the fly" and then execute it - how much more dynamic could it be?

Sure that other Monks will have lots to say about all of this.

Update: So I am basically going to duck 'n cover for now.
