[San-Diego-pm] Perl 5.24

Postfix dereferencing ( $array_ref->@* ) looks like it could be helpful
sugar, but I'm not sure it's really going to solve a lot of problems,
though it might, since they removed the auto-dereferencing in many internal
functions ( keys $hash_ref isn't allowed, it's back to keys %$hash_ref or
the new keys $hash_ref->%* ).  Time will definitely tell on that one.

I'll agree that non-destructive substitution (s///r) is definitely the most
convenient feature they've added in recent memory.

I wish they would figure out smartmatch, so that it moves out of
experimental.  I've found when(){} really helpful for undef, strings,
numbers, and regexes (areas where it's not confusing what is going on).  I
can see how arrays, hashes, functions, and several other types could be
tough to figure out, so make those throw up the warning about experimental
features and let the easy ones work.
