in reply to Creating Nested Functions

I was asked about the possibility of using our $inner; instead of my $inner;. It's doable.

sub outer { ... local our $helper; $helper = sub { ... $helper->(...); ... }; $helper->(@_); }

local still needs to be used to protect the current value of the variable and to clear the reference to the helper sub when outer exits.

I don't see any advantage in localizing $helper instead of &helper.

[moritz]: choroba in python I use jsonschema
[moritz]: I'm sure there's a Perl implementation of it too
[choroba]: it seems Kelp and similar help you a lot with dispatching, but how to do something similar with contents?
[moritz]: like JSON::Schema
[Corion]: ambrus++ # more bugs than lines
[Corion]: That's like "works on my machine" ;-)
[choroba]: I mean, I'd like to say "this path should run this sub, but first it should check the user is authenticated, has the following permissions, and the contents is valid against a given schema
[ambrus]: no, that means I haven't even tried to run it, might not even parse
[ambrus]: so it doesn't work on my machine
[choroba]: i.e. I know JSON::Schema, I'm just curious whether there's a ready solution to plug it into a web service
