Abstract

This TIP proposes the new representation subcommand to info which returns the internal representation of a variable's contents.

Rationale

Inspired by a posting on news:comp.lang.tcl by Victor Wagner, I considered a facility to obtain the internal representation of the value of a variable to be useful.

Proposed Change

Add the new subcommand info representation with the following syntax:

info representation varName

It returns the type of the variable varName or an error, if

Implementation

A patch against Tcl8.4.6 is available [1].
