Yes I get that feeling as well. :-)

I really wanted the latter. :-)

Thanks for the fast answers!
Actually I wanted to get 'unquote inside of a quasiquote; I'm now using:
`(... ,''unquote ...)
It ain't pretty but it appears to do the job! :-)

Ciao a tutti,
When I type `'unquote in DrRacket, an error is thrown:
`'unquote
(X) unquote: expects exactly one expression in: (unquote)
I understand why this error occurs from the way quasiquote is expanded; see
e.g. http://community.schemewiki.org/?scheme-faq-language#qqmacro (I guess
DrRacket works similarly). Still, I feel the result should be just 'unquote.
What do you think?
No, your use of backquote explicitly calls for a search for unquote.
If you want the symbol unquote inside of an unquote, you first need to unquote:
`,'unquote
unquote
(as in comma = unquote).
