Hi All, I'm not sure if you know about this, but there is a discrepancy in the way some folks define macros to use unquote (aka ,). For example,
> (use-modules (system base pmatch)) > (pmatch '(foo "bar") ((foo ,val) (write val) (newline))) => "bar" > (use-modules (ice-9 match)) > (match '(foo "bar") (`(foo ,val) (write val) (newline))) => "bar" Note the difference in the use of quasiquote (aka `) in the pattern for (foo ,val): match syntax uses it, pmatch does not. In Scheme, quasiquote and unquote always come together. Is pmatch syntax in bad taste? I'm looking for opinions. Another example is sxml-match, which omits use of quasiquote. I have written a variation of sxml-match. Should I keep the sxml-match usage, which keeps it compatible with sxml-match, or adopt that used by (ice-9 match)? Matt
