Re^2: A lexical lib pragma?

Your example does show that the effect of "use lib::lexical" is actually, just like local, dynamic instead of lexical. I wouldn't say "global" as the @INC is indeed is restored at the end of the scope. The secondary effect (or tertiary and so on) can be global and/or irreversible but this is brought upon by other action (do/require/use) and not by "use lib::lexical" or the change to @INC itself. And that can be said about any lexical pragma.

I did originally imagine lib::lexical mainly as a syntax sugar for 'local @INC = (..., @INC)'.

The change is seen everywhere in the interpreter, and that's the very definition of global. In any case, it's definitely not lexical! The point is that changes to `@INC` could have very far reaching effects. The fact that the change is temporary doesn't change that. I did originally imagine lib::lexical mainly as a syntax sugar for 'local @INC = (..., @INC)'. That would be FAR clearer to the reader! (But just as dangerous and pointless.)	[reply] [d/l]
