Re^5: Disabling runtime warnings in dynamic scope?

[QM]

Dynamic scoping might be well defined, but Perl Glossary doesn't do a good job. Looking at Lexical Scoping, most people won't be any wiser.

These are general CS terms and easily googled:

http://www.geeksforgeeks.org/static-and-dynamic-scoping/

Perlglossary is from the Camel book, and as such binding for Perl terminology.

Alas the book is not (legally) online.

A local modifies its listed variables to be "local" to the enclosing block, eval, or do FILE --and to any subroutine called from within that block. A local just gives temporary values to global (meaning package) variables. It does notcreate a local variable. This is known as dynamic scoping .
