But if I understand correctly, you're setting up a hash in the stasher's symbol table. Since my case isn't really a script, that's not main ...

Not really sure what you mean.  Of course, the approach isn't limited to main — the latter is just the top-level stash that every "package path" is rooted at.

Essentially, all I wanted to point out is that, in general 

    ${ $::{'PackageA::'}{'PackageB::'}{'PackageC::'}{foo} }

[download]

functionally achieves the same as your symbolic reference 

    ${ *{"PackageA::PackageB::PackageC::foo"} }

[download]

(which could be simplified to  ${"PackageA::PackageB::PackageC::foo"},  btw — or ${"$ns\::foo"} in your specific case)

But, as the former approach doesn't involve symbolic references, it's compatible with use strict, i.e. it doesn't need no strict 'refs'.


P.S.: in several places of the current version of your original node, you're missing the closing curly in the expression ${ *{"${ns}\::foo"}
