I did not find anything mentioning this anywhere, but it is such a basic feature of class based programming, that I can’t imagine it is not there, somewhere, somehow.
class One { method do_it {say 1} }
class Two : isa(One) { method do_it { super()->do_it; say 2} } # or so...
I can do
One::do_it($self)orOne->can('do_it')->($self), but that seems very ugly and against the pattern.
