We should probably document what it means by $c->response->body can accept a
file handle. Like plack specifies the interface it must deal with. Anyone up
to that?
This FH in body thing is something I've been thinking about a lot lately, in
regards to when Catalyst is running under an event loop for example, should
Catalyst stream the Filehandle a non blocking manner. But it would be great to
document this. Also, I am thinking setting the default size when its missing
could really belong to middleware. Plack has some default middleware that does
this:
https://metacpan.org/source/MIYAGAWA/Plack-1.0030/lib/Plack/Middleware/ContentLength.pm
the means it works looks like this
https://metacpan.org/source/MIYAGAWA/Plack-1.0030/lib/Plack/Util.pm#L68
There's a few things in Catalyst.pm that could profitable just use
Plack::Middleware counterparts.
just a thought.

This approach may work for you is the compressed data is actually in a scalar
and not too large. And not too small. YMMV.

No prob. Part of my thing on list reponses is that there is a seed for others
to learn from what was discussed.
I do wonder if there is a sane way to test for an in memory file
handle and give a more appropriate warning, but that is for further
discussion.
