A problem with define-syntax+syntax-case is that you get very verbose syntax definitions, with lots of standard boiler-plate. This makes syntax definitions needlessly hard to read and (less important) more tedious to write. This has tempted some of my Kawa users to use the "legacy" non-hygienic define-macro form, even though I discourage it. Even plain R5RS define-syntax+syntax-rules is ridiculously verbose. One idea I had has this little conveniece macro: (define-syntax define-syntax-case (syntax-rules () ((define-syntax-case name literals . parts) (define-syntax name (lambda form (syntax-case form literals . parts)))))) Typical use - especially nice if #` is availiable: (define-syntax-case NAME () ((_ PVAR ...) #`(... PVAR ...)) Of course people can define this themselves, but it is nicer if it is standard, because then people get used to reading it.
