* tests/dynamic-scope.test, tests/eval.test, tests/r5rs_pitfall.test, tests/srfi-17.test, tests/syncase.test: Wrap tests in module (test-suite test-<file-name without .test>), following a practice that was used on a couple of files already. * tests/dynamic-scope.test (exception:duplicate-binding, exception:bad-binding): New. * tests/dynamic-scope.test, tests/srfi-17.test, tests/syntax.test: Execute syntactically wrong tests using eval. With the upcoming new memoizer this is necessary in order to postpone the syntax check to the actual evaluation of the syntactically wrong form. * tests/syntax.test: Added some test cases and modified one test case.
