Yeah, like this:

I'm not sure if 3) was superflous depending on the definition of "non-pair".

There is an alarming similarity with
for (@hashes) {
.($_)
}
Which doesn't quite use $self! .<>, .[], .{} are method calls, vi

Arrays and hashes would not generally have this restriction, since we

But I would really like to see a declaration of any possible modification

If you are in a method then you get .method and it always works even if $_ is

I also have problems to perceive .method beeing bound to $_ from a
typing point of view: $_ is a dynamic variable in the runtime
environment, while the method i
