: : Can be done with. @{ foo() || bar() } seems preferable to, say,
: : [scalar(foo() || bar())]->[0]->@. :-)
:
: I've seen this possible syntax brought up before at another forum.
:
: where:
:
: @{$hashref->{key}}
:
: would be:
:
: $hashref->{key}->@
:
: This looks counter intuitive, my brain says to dereference the reference at the
: begining, just like you make the reference, in other words, keep it all the
: same:
:
: $hashref->{key}->@ # Deref
: $hashref->{key}->$ # Deref
: $hashref->{key}->% # Deref
: $hashref->{key}->* # Deref
: $hashref->{key}->& # Deref
: $hashref->{key}->\ # Reference
:
: This is just ugly. If it's less line noise and/or punctuation, temp vars is the
: key. I know this has been said before:
:
: $arrayref = $hashref->{key}
:
: @{$arrayref};
: #or
: @$arrayref;
:
: On the other hand, another hacker and I thought up and attempted to write a
: pragma ( attempted because as far as I know, neither of us has touched it in a
: long while ) that degreases line noise in terms of punctuations, sorta. It's
: more verbose anyhow, where:
:
: @{ $hashref->{key} };
:
: becomes:
:
: ARRAY{ $hashref->{key} };
Or:
ARRAY $hashref->{key};
: And the same holds true for SCALAR, HASH, CODE, GLOB and such. It's an
: alternative that hasn't been thought out much, but perhaps kinda neat.
