Named registers were introduced by a patch about six years ago (see changelog) to mimic AllegroCL's behavior. To do that, it obviously wasn't necessary to support names other than strings. I guess a patch allowing other things as names is fine if it doesn't break anything else and follows the usual rules for patches. You'll have to ask Hans. Cheers, Edi.

Hi,

I wondered why :named-register only allows to use strings as name.

I'd like to use a symbol, or, for macro-generated forms, gensyms, because that would be easier for macro-generated forms to associate with the resulting capture index.

Sadly symbols don't work currently because of COPY-SEQ in METHOD CONVERT-COMPOUND-PARSE-TREE ((EQL :NAMED-REGISTER) T)

Even more, the COPY-SEQ destroys EQuality, so I cannot give some string and look for it later on.

What's the reason for the string-requirement? Could we allow symbols, too?

Thanks for all answers.

Regards,

Phil
