Perl 6 provides introspection - that's the ability for its object to be able to report on methods, attributes and inheritances.

And if you run Perl6 without an input file, it goes into a read - interpret - run cycle with each line you type in, rather like Python, Ruby and Tcl do. So we can experiment easily with that introspection.
