Log message:
        (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.
        (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.
