I'm not sure how else to do this. The current implementation returns
char *, which doesn't translate uniformly into the PLs. More
sophisticated implementations--a tree or forest structure including
ANDs and ORs, etc.--are even less uniform to translate into PLs, at
least as far as I can tell.

The way I'm looking at it, this could be added onto SPI at varying
degrees of sophistication, but there would still be PL-specific
bindings for it, each of which would involve a PL-specific
implementation effort.

What big things have I missed here?

Cheers,
David.
