in thread PadWalker's closed_over - but for our variables?

I attempt to stay as close to perlglossary as possible.

The term "lexical" is messed up tho.

edit

https://perldoc.perl.org/perlglossary#global

In Perl, only certain special variables are truly global—most variables (and all subroutines) exist only in the current package.

    No. Maybe imprecise since there two kinds of lexically-scoped variables, but not messed up.

    Don't do that by by reinventing what global means (or basing yourself on a passage that does that). *That* would be messed up.

    $_ and similar have been called superglobals.

      perlglossary is explicit that our-vars are not "lexicals".

      https://perldoc.perl.org/perlglossary#lexical-variable

      A variable subject to lexical scoping, declared by my. Often just called a “lexical”. (The our declaration declares a lexically scoped name for a global variable, which is not itself a lexical variable.)

      I didn't, I cited perlglossary which was written by Larry.

      > $_ and similar have been called superglobals.

      never heard the term superglobal, any reference?
