Guile Emacs Lisp previously kept macros in a separate macro slot; now
macros are stored as macro objects in the function slot for
compatibility with other implementations.
* module/language/elisp/compile-tree-il.scm (macro-slot): Remove.
(is-macro?): Check that the argument is a symbol. Now-unnecessary
check removed in `compile-tree-il'.
(macro?, define-macro!, get-macro): Store macro definitions in the
function slot, not in a separate macro slot.
* module/language/elisp/runtime.scm (built-in-macro): Wrap the macro
function in a macro object (i.e., cons the symbol `macro' onto it).
* module/language/elisp/runtime/function-slot.scm: Move contents to
"subrs.scm". Re-export function and macro definitions instead of
defining functions directly in this module.
* module/language/elisp/runtime/macro-slot.scm: Move contents to
"macros.scm" and remove.
* module/language/elisp/runtime/macros.scm: New file containing macro
definitions from "macro-slot.scm".
* module/language/elisp/runtime/subrs.scm: New file containing function
definitions from "function-slot.scm".
* module/language/elisp/bindings.scm:
* module/language/elisp/compile-tree-il.scm:
* module/language/elisp/lexer.scm:
* module/language/elisp/parser.scm:
* module/language/elisp/runtime.scm:
* module/language/elisp/runtime/function-slot.scm:
* module/language/elisp/runtime/macro-slot.scm: Ensure that all
top-level forms and comments are separated by exactly one newline.
Remove blank lines in most procedure bodies. Delete trailing
whitespace.
* module/language/elisp/runtime/macro-slot.scm (or, and): Fix one-arg
case to return the arg as-is.
* module/language/elisp/runtime.scm (nil-value): Fix to be #nil.
* module/language/elisp/README: Document new features.
* module/language/elisp/runtime/function-slot.scm: Implement funcall, apply and
eval by using the existing compiler code.
* test-suite/tests/elisp-compiler.test: Test those.
* module/language/elisp/README: Document it.
* module/language/elisp/compile-tree-il.scm: Moved ensure-fluid! to runtime function.
* module/language/elisp/runtime.scm: Runtime functions to support dynamic value access.
* module/language/elisp/runtime/function-slot.scm: Defined the built-ins.
* test-suite/tests/elisp-compiler.test: Test them.
* module/language/elisp/README: Document it and some further ideas written down.
* module/language/elisp/compile-tree-il.scm: Implement prog1, dolist.
* module/language/elisp/runtime/macro-slot.scm: prog2 and dotimes.
* test-suite/tests/elisp-compiler.test: Test prog1, prog2, dotimes, dolist.
* module/language/elisp/README: Document it.
* module/language/elisp/compile-tree-il.scm: Implement defmacro and expansion.
* module/language/elisp/runtime/macro-slot.scm: New module to keep definitions.
* test-suite/Makefile.am: Add elisp-compiler.test to list of tests.
* test-suite/tests/elisp-compiler.test: Basic macro tests.
* module/language/elisp/runtime/function-slot.scm: Fixed errors in number preds.
* test-suite/tests/elisp-compiler.test: Test built-ins already implemented.
