While I agree it's a bad idea to use symbols that can't be readily
typed as part of the language syntax, I think Terry's broader point
that anything which *can* be implemented outside the core usually
*should* be implemented outside the core (at least as a
proof-of-concept) is a good one.

This particular proposal sounds to me like something that shouldn't be implemented at all. We don't need another split in the community over how to spell operators.
 
Hy shows it is possible to implement a Lisp on top of the CPython
runtime,

It wasn't proposed as a serious feature on python-ideas.
 
so folks should certainly be capable of implementing a
Python-with-Unicode-symbols on top of existing Python runtimes without
needing the blessing of the core development team.
 
Terry *is* asking for a blessing of the .pyu extension by the core team. (Although it seems he wouldn't be too upset if he didn't get it. :-)
