Description

Lexical::Var implements lexical scoping of subroutines. Although it can be used directly, it is mainly intended to be infrastructure for modules that manage namespaces.

This module influences the meaning of single-part subroutine names that appear directly in code, such as "&foo" and "foo(123)". Normally, in the absence of any particular declaration, these would refer to the subroutine of that name located in the current package. A Lexical::Sub declaration can change this to refer to any particular subroutine, bypassing the package system entirely. A subroutine name that includes an explicit package part, such as "&main::foo", always refers to the subroutine in the specified package, and is unaffected by this module. A symbolic reference through a string value, such as "&{'foo'}", also looks in the package system, and so is unaffected by this module.

The types of name that can be influenced are scalar ("$foo"), array ("@foo"), hash ("%foo"), subroutine ("&foo"), and glob ("*foo").
