Re^4: A lexical lib pragma?

I do want it to affect 'use' too, as well as require/do.

Note that LanX's Filter::Inject is different from a traditional source filter...

Color me intrigued. Checking the module as well as the talk. Thanks!

I do want it to affect 'use' too, as well as require/do. In that case I think you'll have to use B::Hooks::EndOfScope. For dynamic scoping at runtime, I imagine `Filter::Inject` could be used to inject a piece of code that basically makes a local change to @INC. For either compile or runtime, if you want it to be lexically scoped, I still can't think of a better way than an @INC hook and %^H. Although I also still can't imagine a use case for `use` with a lexically scoped @INC `:-/`	[reply] [d/l] [select]
