Env-Path Perl script

Publisher review:
Env-Path simply defines a set of methods a path variable may call on itself without changing the variable's value or other semantics. Env::Path presents an object-oriented interface to "path variables", defined as that subclass of environment variables which name an ordered list of filesystem elements separated by a platform-standard separator (typically ':' on UNIX and ';' on Windows).Of course, core Perl constructs such $ENV{PATH} .= ":/usr/local/bin"; will suffice for most uses. Env::Path is for the others; cases where you need to insert or remove interior path entries, strip redundancies, operate on a pathvar without having to know whether the current platform uses ":" or ";", operate on a pathvar which may have a different name on different platforms, etc.The OO interface is slightly unusual in that the environment variable is itself the object, and the constructor is Env::Path->AUTOLOAD; thus Env::Path->MANPATH; will bless $ENV{MANPATH} into its package while leaving it otherwise unmodified (with the exception of possible autovivification). Unlike most objects, this is a scalar and thus can have only one attribute; its value.In other words, Env::Path simply defines a set of methods a path variable may call on itself without changing the variable's value or other semantics.
