[IronPython] Trying to set methods on "built-in" classes failssilently

Standard practice or not, this begs the question of whether it should be allowed at all.  I would argue against it:
* security issue
* silent fails mask unexpected behavior
However, adding *new* members doesn't, to my knowledge, present a security risk.  As a comparison, MSH allows new members and aliases to be overlayed on top of existing types, but I don't know whether or not it chokes when attempting to override an existing member.  It may be worthwhile to agree with the MSH team on a strategy.

I suspect it's not something anyone's likely to come across often, but
if you try to rebind a method on a built-in class,  no exception will be
thrown but it will not be changed.  An example:
