Gee, I should crawl out from under my rock and look around every now and
then. :) I had no idea so many implementations had adopted
case-sensitive syntax as the default.
But the diversity of implementations argues for allowing implementations
the choice to set the default.
I should comment, since several implementations seem to do it, that my
experience with MIT/GNU Scheme's case-folding option (a dynamically
bound global variable) has been unpleasant. It has caused confusion for
users on numerous occasions, and sometimes non-obvious bugs. That's why
I'm advocating a mechanism that binds the option directly into the text.
