I very much doubt you'll be able to inherit from the builtin types.

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 C of
something and the type(s) that C returns?
In keeping with the lower case C and C exa

Typically contains an object with both string and integer conversions.

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

That you need some *serious* psychotherapy! ;-)
Actually, it would mean that $foo can only contain values
whose type is simultaneously C and C.

and this just jumped out at me:
class Foo {
private string|int bar;
static create(string|int newBar) {
bar = newBar;
}
}
In other words, as I understand it, you can type the variable bar as
either an int or a string.
Aside from simply, "my $bar;", w
