ASSERT_SYNTAX to signal syntax errors. Avoid unnecessary consing
when creating the memoized code.
(scm_m_atbind): Reversed the order, in which the init expressions
are stored and executed. The order of execution is now equal to
the order in which the initializers of the let-forms are executed.
Use check_bindings and transform_bindings.
(SCM_CEVAL): Eliminated SCM_NIMP in favor of more appropriate
!SCM_NULLP. Added some comments.
* test-suite/tests/dynamic-scope.test (exception:missing-expr):
Introduced temporarily until all memoizers use the new way of error
reporting.
* 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.
