Re: Modules to reduce syntax?

[perlfan]

Util::H2O will take this,

  my $ref = { foo => $bar => 'baz' };
  printf "%s\n", $ref->{'foo'}{$bar};

And let you do this:

  use Util::H2O qw/h2o/;
  my $ref = h2o -recurse, { foo => $bar => 'herp' };
  printf "%s\n", $ref->foo->$bar;

If you use a lot hash references, it can remove a significant amount of typing and cruft simply by doing away with the curly braces. The reduction in typing and file size from these 2 characters quickly adds up. enjoy!

That's a Pyrrhic victory from level two onwards.

Curlies {} are "spared" for mandatory arrows -> for the price of init and OO overhead.

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.
