Next step - that code compiles okay. But it doesn't work when run ...

I'm getting the following errors:

Interpreting music...
warning: cannot find property type-check for `capoVertical'
(translation-type?).  perhaps a typing error?
warning: doing assignment anyway
warning: cannot find property type-check for `capoPitch'
(translation-type?).  perhaps a typing error?
warning: doing assignment anyway

But I've added capoVertical and capoPitch to the ADD_TRANSLATOR section,
and I've added them to define-context-properties.scm. So why can't it
find it? Or is it that I've installed 2.15 locally, and it's finding the
scheme code for 2.14 or 2.12? Unlikely, I would have thought, wouldn't
that cause a crash?

Is there a C++ function that will dump the contents of a scheme variable
to stdout?

Cheers,
Wol
