* Fixed typo in the docs for serialization (serializable-struct/version → serializable-struct/versions)
* Fixed typo in scribble documentation (head pattern → a-pattern)
* Made the order of the argument descriptions match the order of the arguments in the documentation for import and export
* Wrong contract for syntax-local-value in the documentation.
* Clarified signature in documentation for expand-import, expand-export and pre-expand-export
* Corrected typo in documentation for "for".
* Fixed error message for function which seems to have been renamed in the docs
* Fixed typo in a comment in the tests
* Fixed a typo in the documentation for set-subtract.
* Use double ellipses for the free-id-table-set*, free-id-table-set*!, bound-id-table-set* and bound-id-table-set*! operations
Change the one expansion mode as far as I can tell) that disables
lifts so that lifts are now allowed, which means that
`(syntax-transforming?)` implies `(syntax-transforming--with-lifts?)`.
The old documentation incorrectly characterized when lifts
were allowed. Ryan noticed the documentation problem, and that
observation led to this simplication.
Port `examples`, `interactions`, etc., to use the new `examples`
form of `scribble/examples`. The main intended effect is to ensure
that errors are produced by examples only as specifically
indicated.
When an internal-definition context is used with `local-expand`, the
any binding added to the context affect expansion, but the binding do
not appear in the expansion. As a result, Check Syntax was unable to
draw an arrow from the `s` use to its binding in
(class object%
(define-struct s ())
s)
The general solution is to add the internal-definition context's
bindings to the expansion as a 'disappeared-bindings property. The new
`internal-definitionc-context-track` function does that using a new
`internal-definition-context-binding-identifier` primitive.
The `prop:expansion-contexts` property can control the expansion
of a rename transformer in much the same that conditionals on
`(syntax-local-context)` can control the expansion of other
transformers.
Genereating a use-site scope, instead of a macro-introduction scope,
prevents the scope's presense from triggering a #f result from
`syntax-original?`.
