how to get rid of ruby's warning: already initialized constant

Question

I'm trying to redefine a gem's constant dynamically so I don't need to modify the gem itself.

require 'xmlrpc/client'

XMLRPC::Config.const_set("ENABLE_NIL_PARSER", true)

warning: already initialized constant ENABLE_NIL_PARSER

Is it possible to get rid of the warning?

The easy way:

v, $VERBOSE = $VERBOSE, nil
# code goes here
$VERBOSE = v
