I received some convincing arguments that the original quasi proposal fell short as a DSL scheme. Whether a full-fledged DSL scheme is desired or not, I don't know, but I read up on scheme macros and put together an alternative semantics that I hope gets the strengths in flexibility and performance of scheme macros while preserving the encapsulation and security goals of SES, and having a syntax that should be familiar to PHP and perl users.
It is a significantly more complex proposal so I broke the semantics into three sections: free variable analysis, alpha-renaming, and hygienic macros, and put together a draft implementation of each. The alternative proposal is at http://wiki.ecmascript.org/doku.php?id=strawman:quasis-alt and that page links to the two supporting documents. At the top of each are links to source code and tests. Even if the extra complexity is prohibitive, hopefully this demonstrates that the original proposal can be extended in the future should DSL support in ecmascript become a desideratum. cheers, mike _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
