Nicely done, Kon. For those who haven't seen Kon's modification yet,
it uses cond-expand to see if syntax-case is installed when hart is
loaded: if so, it provides high-l
In release/3 is hart 1.3.0 which supports syntax-case.

This is not bad:

It's CL, not Scheme, but I believe define-macro comes from CL anyways.
You can ignore the part before the anchor that link goes to.

I'm afraid that means very little to me. Are you saying that all
things that use low-level macros die when you load syntax-case?
I'd like to understand this too, even if the hart problem is solved
another way.

Is there a way I can alter hart so that it will play better with code
that uses higher-level macro systems? I'd rather not rewrite it in
syntax-case (though it's really not very much macro cod
