No. The above "lowlevel" C<cos> isn't aware of C<base> nor of C<$_> and
nothing is autogenerated in Parrot. The C<cos> is something like:
class __parrot_core::Float {
multi sub cos(Float x) returns Float ...
}
This is presumably inherited by C<class P6Num> (the Parrot PMC) and
bound to:
multi sub *cos(Num $x) returns Num
at the Perl6 level.
