SYNOPSIS:
    UNDECLARE $variable

DESCRIPTION:
    Explicitly undeclare a variable. This is usually not needed,
    as voxren will automatically release local variables.
    However, if you want to change type of an existing variable
    or have temporarily created a variable in the $root scope,
    undeclare might be useful.
    Note, that it is considered bad style to communicate between
    subroutines using global variables. Either give them as
    parameters, or where this is not feasible, use the $parent
    scoping prefix to access variables further up the hierarchy.
