Hi all,
I found myself wanting to check whether some code had a $SIG{__DIE__} in
it and realized I still had this silly module in my experiments
directory.
This throws an error whenever a $SIG{__DIE__} is assigned without a
local(). Potentially useful in tests, or just via -M...
(Yes,

From the code, I would have no idea what this does without a
fair bit of perldoc-ing. How about some comments? bad bunny?
Oh, so you want features? I'm not sure what constitutes a fair bit of
documentation though

it could be documented as a suggested use case for Acme::Landmine
Acme::landmine uses tie (on %SIG - does that work?) to blow up when the
variable is accessed, but I only want to know when it is globally
deleted. How does that work?

Yes, tying %SIG is possible, and even tying entries in the %SIG hash. See
Sig::PackageScoped for an entirely insane example.

yes, absolutely. Until I saw your usage example I did not get how you
use this handy tool. Since the localizing is the thing you

Hi All.
I have this module on CPAN, Data::ParseBinary.
now I want to add a library of pre-prepared format. For example, a
parser/builder for BMP files.
The question is, how do I call it?
some options that I though about:

Furthermore, you're enforcing a stricture, rather than enhancing Carp.
Here's a briefly considered suggestion:
perl -Mstrict::sigdie yourprogram.pl
Maybe some day this will be a best practice:
use strict;
use strict::sig::die;
