my question is: will it still be possible to write a (er-) macro that creates new identifiers like define-record does?
In most hygienic macro systems it's possible to "break" hygiene for the purposes of introducing identifiers. I don't believe syntax-rules has a way to do this, syntax-case (through the syntax->datum etc) and explicit renaming macros definitely do. Explicit renaming macros are very similar to the low level macros of define-macro except for the fact that you must "explicitly rename" identifiers to be hygienic. But, you don't have to rename _all_ of them should you want to introduce an identifier. -- Andrew Gwozdziewycz [EMAIL PROTECTED] http://www.apgwoz.com | http://www.photub.com
