I think the new meta-operators will be part of the grokking. I think
there are 3 or 4 used in that line:

- ->
Z+ (might actually count as 2 since the + is modifying the Z)
...
*

at least I think -> is a meta-operator.

I say it's only unreadable because we don't know the language.

There were vast chunks of Perl 5 that I couldn't understand.

I think why I've liked Perl is that you can have various dialects of it
or at least different fluencies and still be useful (from baby-talk Perl
all the way to crazy-insane golf Perl).

Now, should this be production code? Don't know, depends upon how well
your fellow coders know the language.
