@m[0;1] is a multidim deref, referencing the 4.
Referencing the 2, I hope?
Doh!
Yes, the 2.
Really?
@m here has _single_ array-ref so
@m[0] returns that

No.

I'm not familiar with the reasoning behind the current situation, but
I'm struggling to come up with any good reasons for keeping it.
Consider the alternative:

Assuming you write the subset coroutine above, how about

I was thinking on the drive home how to write some of the File::Spec

one of a bunch of mixins (maybe OS::unix, OS::win32, OS::vms, etc).
That way, you could multimethod the various functions, using junctions
