+ 2004-04-10  Miles Bader  <address@hidden>
+ 
+       * eval.c (Fspecialp): New function.
+       (syms_of_eval): Initialize it.
+ 
+ 2004-04-03  Miles Bader  <address@hidden>
+ 
+       * eval.c (Feval): If a variable isn't bound lexically, fall back
+       to looking it up dynamically even if it isn't declared special.
+ 
+ 2002-08-26  Miles Bader  <address@hidden>
+ 
+       * bytecode.c (Fbyte_code): Fsub1 can GC, so protect it.
+ 
+ 2002-06-12  Miles Bader  <address@hidden>
+ 
+       Lexical binding changes to the byte-code interpreter:
+ 
+       * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, Bvec_ref, Bvec_set)
+       (BdiscardN): New constants. 
+       (exec_byte_code): Renamed from `Fbyte_code'.
+       Implement above new bytecodes.
+       Add ARGS-TEMPLATE, NARGS and ARGS parameters, and optionally use
+       them push initial args on the stack.
+       (Fbyte_code): New function, just call `exec_byte_code'.
+       Add additional optional arguments for `exec_byte_code'.
+       (Qand_optional, Qand_rest): New extern declarations.
+       * eval.c (Fcurry, Ffunctionp): New functions.
+       (syms_of_eval): Initialize them.
+       (funcall_lambda): Call `exec_byte_code' instead of Fbyte_code.
+       If a compiled-function object has a `push-args' slot, call the
+       byte-code interpreter without binding any arguments.
+       (Ffuncall): Add support for curried functions.
+       * lisp.h (Fbyte_code): Declare max-args as MANY.
+       (exec_byte_code): New declaration.
+ 
+       Lexical binding changes to the lisp interpreter:
+ 
+       * lisp.h (struct Lisp_Symbol): Add `declared_special' field.
+       (apply_lambda): Add new 3rd arg to decl.
+       * alloc.c (Fmake_symbol): Initialize `declared_special' field.
+       * eval.c (Vinterpreter_lexical_environment): New variable.
+       (syms_of_eval): Initialize it.
+       (Fsetq): Modify SYM's lexical binding if appropriate.
+       (Ffunction): Return a closure if within a lexical environment.
+       (Flet, FletX): Lexically bind non-defvar'd variables if inside a
+       lexical environment.
+       (Feval): Return lexical binding of variables, if they have one.
+       Pass current lexical environment to embedded lambdas.  Handle closures.
+       (Ffuncall): Pass nil lexical environment to lambdas.  Handle closures.
+       (funcall_lambda): Add new LEXENV argument, and lexically bind
+       arguments if it's non-nil.  Bind `interpreter-lexenv' if it changed.
+       (apply_lambda): Add new LEXENV argument and pass it to funcall_lambda.
+       (Fdefvaralias, Fdefvar, Fdefconst): Mark the variable as special.
+       (Qinternal_interpreter_environment, Qclosure): New constants.
+       (syms_of_eval): Initialize them.
+       (Fdefun, Fdefmacro): Use a closure if lexical binding is active.
+       * lread.c (defvar_bool, defvar_lisp_nopro, defvar_per_buffer) 
+       (defvar_kboard, defvar_int): Mark the variable as special.
+       (Vlexical_binding, Qlexical_binding): New variables.
+       (syms_of_lread): Initialize them.
+       (Fload): Bind `lexically-bound' to nil unless specified otherwise
+       in the file header.
+       (lisp_file_lexically_bound_p): New function.
+       (Qinternal_interpreter_environment): New variable.
+       * doc.c (Qclosure): New extern declaration.
+       (Fdocumentation, store_function_docstring): Handle interpreted
+       closures.
