That's a cut'n'paste error in pdd15 - at least now. All vtable methods,
which are explicitely in ParrotClass/ParrotObject aren't overridable.
You might have a look at classes/parrotobject.c:
...
Parrot_delegate_clone,
Parrot_ParrotObject_find_method,
Parrot_delegate_get_integer,
Parrot_delegate_get_integer_keyed,
...
But there will be of course some AUTOLOAD scheme. And you can simulate
one with exceptions:
.sub _main
$P0 = newclass "A"
$I0 = find_type "A"
.local pmc obj
obj = new $I0
.local pmc exh
newsub exh, .Exception_Handler, _exh
set_eh exh
obj."meth"(42)
print "done\n"
end
.end
.sub _exh
print "exh\n"
print "exh - wanted '"
print S0
print "'\n"
$P0 = find_global "A", "__f42"
invoke $P0
.end
.namespace ["A"]
.sub __f42 method
print "42\n"
.end
$ parrot o.imc
exh - wanted 'meth'
42
done
