* module/language/elisp/boot.el (integerp, wholenump): Call `integer?'
before `exact?' so that these predicates return nil for non-numbers
instead of signalling an error.
* module/language/elisp/boot.el (%catch): New variable.
(catch): Bind `%catch' to `t' during the evaluation of `body'. Call
`throw' instead of signalling an exception directly.
(throw): Signal a `no-catch' error if there is no `catch' to throw to.
* module/language/elisp/boot.el (throw): Define an `error-conditions'
property for this symbol.
(catch): Define in terms of `condition-case' instead of using Guile
exceptions directly.
(throw): Signal a `throw' condition instead of throwing a Guile
exception directly.
* module/language/elisp/boot.el (error, wrong-type-argument, no-catch,
invalid-function): Define `error-conditions' properties for these
standard error symbols.
* module/language/elisp/boot.el (signal): Accept only two arguments, and
throw an `elisp-condition' exception instead of an `elisp-error'
exception.
(condition-case): New macro.
* module/language/elisp/boot.el (lexical-let, lexical-let*): New macros.
* module/language/elisp/compile-tree-il.scm (bind-lexically?): Remove
the check for a `lexical' flag, since `lexical-let' and `lexical-let*'
are no longer special operators.
(compile-lexical-let, compile-lexical-let*): Remove.
* module/language/elisp/runtime/function-slot.scm: Update module
definition.
* module/language/elisp/boot.el (prog1, cond, or, catch): Use `let' with
`lexical' declarations instead of `lexical-let'.
(%plist-put): Use `let' instead of `lexical-let', since "boot.el" now
uses lexical binding by default.
* module/language/elisp/boot.el (null, consp, listp, car, cdr)
(make-symbol, signal): Use `%funcall' instead of `funcall' or `fset'.
(symbolp, symbol-function, eval): Use `%funcall', since `funcall' now
calls these functions.
(functionp, %indirect-function): New functions.
(funcall): Define in terms of `%funcall' and `%indirect-function'.
(apply): New function. Previously defined in
"module/language/elisp/runtime/subrs.scm".
(fset): If `definition' is not a function, set the function cell of
`symbol' to an falias for `definition'.
* module/language/elisp/falias.scm: New file.
* module/language/elisp/subrs.scm: Remove file.
(apply): Remove. Now defined in "boot.el".
* module/language/elisp/runtime/function-slot.scm: Update module
definition.
* module/Makefile.am: Update.
* module/language/elisp/runtime/macros.scm: Remove.
(macro-lambda, macro-prog1, macro-prog2, macro-cond, macro-and,
macro-or, macro-catch, macro-unwind-protect): Rewrite in Elisp and
move to...
* module/language/elisp/boot.el (lambda, prog1, prog2, cond, and, or,
catch, unwind-protect): ...here.
(eval-and-compile): New macro.
(funcall, fset, null, consp, listp, car, cdr, make-symbol-signal):
Wrap definitions in an `eval-and-compile' form so that they can be
used by the rewritten macros.
* module/language/elisp/runtime.scm: Remove `built-in-macro'.
* module/language/elisp/Makefile.am: Remove
module/language/elisp/runtime/macros.scm from `ELISP_LANG_SOURCES'.
