Perl module for static variables without namespace pollution
|
|
|
|
Lexical::Var and Lexical::Sub implement lexical scoping of static variables and
|
|
subroutines. Although it can be used directly, it is mainly intended to be
|
|
infrastructure for modules that export particular objects.
|
|
|
|
Lexical::Var only manages variables of static duration (the kind of duration
|
|
that our and state variables have). To get a fresh variable for each invocation
|
|
of a function, use my.
|
|
|
|
Lexical::Sub is implemented through the mechanism of Lexical::Var. Its distinct
|
|
name and declaration syntax exist to make lexical subroutine declarations
|
|
clearer.
