http://en.m.wikipedia.org/wiki/Scope_(computer_science) 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.

updateSee also perlsub#Temporary-Values-via-local() 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 .
