I still have the same end goal, but I believe there must be a way to
obtain it without too much disturbance.  Case-sensitivity, for
example, may be a tool feature rather than a language feature, or it
may be a user option or a langage-level choice.  (Not that I've
figured out exactly how to do this, but TeachScheme makes this an
option.)  Note that case-sensitivity is also controversial: the Alice
folks found it a problem, but the VPython folks have not confirmed
this (while they did confirm the integer division trap).
