Mark H Weaver e7cf0457d7 Support => within case, and improve error messages for cond and case ... * module/ice-9/boot-9.scm (cond, case): Reimplement using syntax-case, with improved error messages and support for '=>' within 'case' as mandated by the R7RS. Add warnings for duplicate case datums and case datums that cannot be meaningfully compared using 'eqv?'. * module/system/base/message.scm (%warning-types): Add 'bad-case-datum' and 'duplicate-case-datum' warning types. * test-suite/tests/syntax.test (cond, case): Update tests to reflect improved error reporting. Add tests for '=>' within 'case'. * test-suite/tests/tree-il.test (partial evaluation): Update tests to reflect changes in how 'case' is expanded. * doc/ref/api-control.texi (Conditionals): Document '=>' within 'case'.		2012-02-08 16:27:48 -05:00
