Re^3: Modules to reduce syntax?

[perlfan]

>Pyrrhic victory

perhaps a tad hyperbolic? OP asked for reduction in syntax (I read it as more readable) - not even "less typing"; but the only thing I can assuredly tell you is that I tend to use this module a lot nowadays. And it is true that eliminating a paired set of curlies in exchange for some dereference syntax is worth it to me; and "overhead" (whatever that means to the reader) is generally never something I even look at. My optimizations happen on the algorithmic or complexity level; IOW I avoid nesting loops in favor of ... hashes (and references to such) :-) In any case, I should have added a YMMV.

well you said

and that's not the case from the second level on.

This can be easily overlooked, hence my remark.

[perlfan]

The -recurse option to h2o creates accessors for all levels of hash; though I have not tried to see if it works for something like,

  my $ref = {
    foo => { bar => [ baz => 1, herp => 2, derp => 3 ], },
  };

Or maybe I don't know what you mean by, from the second level on.

Your first level deref with H2O

$ref->foo

is 2 characters shorter than

$ref->{foo}

but that's it!

No more gains for further levels

$ref->foo->$bar->baz->bla °

vs

$ref->{foo}{$bar}{baz}{bla}

is still only 2 characters better.

°) hypothesized, I've never used or tested this.
