I believe that the subject there is my brother in the first sentence

As I understood (please correct me if I'm wrong), the difference between
does and but was that does modifies the existing object in-place,
and does creates a copy with the new mixin
I¹m only an amateur linguist, but from a linguistic point of view, there are

The term ³subject² has many meanings in English, including ³topic². But
from a grammatical and linguistic standpoint, there are only two meanings of

Hello all,
I have been going over the Synopsis, and I cannot find block labels
mentioned anywhere. I was under the impression that if it is not
mentioned, then it can be assumed to be the same as perl5. However, I
wonder if this is the case with labels given that everybody wants the
colon.

This works too:
map { ;$_ = $_ } @foo;
But () is still only a grouper, so this won't do:
map { ($_ = $_) } @foo;
Does this make sense?
A lot! BTW, is it possible to distinguish methods and subs
from the toplevel, too? That little inference

Nope, Aaron was right here, since you're not trying to mutate $self;
you're just trying to return a new $self with other capabilities.

Given that next throws a control-exception that is handled by the
