[parenscript-devel] How to generate element[i].childNodes[0].nodeValue

[Vladimir Sedach]

This is actually a cool example. I never thought about using
SLOT-VALUE that way. I'm rewriting the reference manual right now
(should be done in a couple of days), I'll make sure to mention this.

The way the @ macro works is actually just by quoting all symbols it
finds and passing its arguments to SLOT-VALUE.

One thing is that I renamed SLOT-VALUE to GET-PROPERTY in the
repository version, since what the form did really didn't have
anything in common with Common Lisp's SLOT-VALUE, as someone pointed
out.

Thanks,
Vladimir
