I thought about that one too, but it also follows @ISA. You can fix that with this:

do { local @ISA; __PACKAGE__->can("do_$type") }->();

Much smoke. Many mirrors. In fact, I'd cache the result too:

BEGIN {
  my %cache;
  sub do_it {
    my $func = shift;
    ($cache{$func} ||= do { local @ISA; __PACKAGE__->can("do_$fun") })
      ->(@_);
  }
}
...
do_it("function", $arg1, $arg2, @more_args);
