Has any thought yet gone into the builtin Perl types and what they will
be called in Perl 6? Will there be a difference between the Cref() of
something and the type(s) that Cisa() returns?
In keeping with the lower

I imagine that type specifiers require that values assigned to
the corresponding variable satisfy: value.isa(type). Using a
superposition as a type means that the result of that test comes

I'd expect so.
I'm forgetting what has been said about $!

In other words, as I understand it, you can type the variable bar as
either an int or a string.

Well, I'm still hopeful Larry will approve superpositions. In which case,
since types in Perl 6 are first-class, you would be able to write
the same thing something like:
