Great explanations. Yes, I was confused about the difference between "load strict.pm file" and "enable strictures".

But once I actually went over strict.pm, I found another rabbit hole of multiple $^H "bits". So I checked which stricture bits are enabled by "use VERSION" vs "use strict". As it turns out, both set $^H = 256.

In fact, I'm not really sure how to set anything other than 256 (I've tried "use strict; no strict refs" etc), so this begs the further question of whether those strict tags actually work as advertised.

Right. Depends on the device I guess; and now that I think about it, also on whether perl was actually installed with its core modules (e.g. libperl might have been statically linked into an app, but that's a whole different can of worms). Good to know.
