In addition to this, I'd also say be very careful about
redefining methods in core classes.  Same reason - they are
written in C.  Many times the C code bypasses the standard
method call mechanism and calls other C code methods directly
so if you redefine you may not get what you want.  An extreme
example is Regexp#=~.  See what happens when you try to
override it - you'll get inconsistent results even if only ruby
code calls it.
