Therefore, it does not "capture" these unquotes: they cannot "belong" to this quote. The comma and quote "cancel out", so the only effect -of comma-quote is to add one level of unquoting. So for instance, whereas in -'(a b c '(,d)), the subsitution of d belongs to the inner quote (it is unquoted -by the leftmost comma which belongs to the innermost quote) by contrast, -in '(a b c '(,',d)) the d is now one comma removed from the leftmost comma and -thus the substitution of d belongs to the outer quote. +of comma-quote is to add one level of unquoting.

In other dialects of Lisp, this would be written `(a b c `(,',d)), making it explicit which kind of quote is being specified. TXR Lisp works out which kind of quote to use internally. |
