record-case?

[Noah Lavine]

Hello,

I was just reading module/language/tree-il/compile-glil.scm, and I
noticed it used a construct called 'record-case'. It looked neat, but
I didn't see documentation for it in any of the obvious places in the
manual (the section on records or the pattern-matching section). Is it
public? If so, is there documentation somewhere?

Thanks,
Noah Lavine
