Comment(by whiteknight):
As is my understanding, I don't think this should be supported. This is an
attempt to redefine an existing VTABLE. I think you probably want a
subclass like this:
{{{
.HLL 'parrot'
.namespace ['MyString']
.sub get_string :vtable
.return('')
.end
.namespace []
.sub foo :main
$P1 = new 'MyString'
$P1 = 'not '
$S0 = $P1
print $S0
say "ok 1"
.end
}}}
The only PMC type that checks for overrides is the Object PMC. The String
PMC doesn't have any facilities to check for them.
