* Advice package now signals error if the user attempts to advise
anything but an compound procedure.
* Continuation parser keeps track of the type of the previous stack
frame. This information is used as context in some situations.
This mechanism replaces special-purpose flag `allow-next-extended?'.
* Continuation parser slightly reorganized and commented to make it
easier to understand.
* Debugger modified to provide more flexible control over use of
history information, to provide more detailed information about
stack frames, and to make it more self-explanatory. Also knows
about "simulated" compiled-code environment frames, and ignores
them.
* The environment inspector has been modified to make it more
self-explanatory. The N command has been replaced by an O command
like that of the debugger.
* `pretty-print' now has additional optional argument that specifies
an indentation for the printed expression. If given, the output is
indented by that many columns.
* The emacs interface now has a hook for evaluating arbitrary
emacs-lisp expressions. This is used to provide a better debugger
interface.
**** This requires "xscheme.el" version 1.26 or later. ****
* `stack-frame/debugging-info' now returns a third value,
"subexpression", which indicates the subexpression of the expression
that the next later subproblem is evaluating.
* The lambda abstraction now forces the use of internal lambda
expressions for auxiliary variables. This is required for correct
semantics of `letrec'.
* `make-lambda' now does error-checking on its parameter-list
arguments, which disallows duplicates in the parameter lists.
* The `procedure' abstraction has been split off into a separate file.
`procedure-arity' has been modified to handle entities correctly.
A new datatype, `apply-hook', is like entities except that it
doesn't pass itself to the handler. `compound-procedure' operations
have been removed from the global environment; use generic
operations instead.
* The unsyntaxer has a new entry point, `unsyntax-with-substitutions',
which allows subexpressions of an expression to be replaced in the
output with arbitrary objects.
* Removed `dynamic-state-let' from `system-global-syntax-table'.
* The syntaxer now disallows the use of syntactic keywords as
variables. This applies to references, bindings, and definitions.
* The syntaxer signals an error if the name of a named `let' is also
one of its bound variables.
* The syntaxer signals an error if there are duplicates in the
parameters of a lambda expression.
* Compiled-code environments that do not have interpreter-compatible
ancestors now simulate such ancestors for debugging convenience.
The simulated ancestor is the closing environment of the compiled
code, if known, otherwise it is the system global environment.
