I like the intent of EVAL-WHEN-NON-TOP-LEVEL:GENERALIZE-EVAL but have some
If "the file compiler" means COMPILE-FILE, why not say COMPILE-FILE? I'm
sure you don't mean to refer to, say, a C compiler written in Common Lisp,
even though it might be a file compiler.
Instead of "a top-level form in the file compiler", say "a top-level form
processed by COMPILE-FILE." In any case, you don't mean to talk about one
of the expressions that occur in the source code that defines COMPILE-FILE.
For an EVAL-WHEN form that is not a top-level form in the file compiler
(that is, one of: in the interpreter; in COMPILE; or in the file
compiler but not at top-level) ...
The "(that is, ..." clauses are neither exhaustive or appropriate. I think
you really mean "all other cases". I don't think you can have an EVAL-WHEN
that is 'at top level' to COMPILE since COMPILE takes functions or lambda
expressions. It's possible to think of a version of COMPILE-FILE that
produces things that are then 'interpreted' to some extent (byte-code
interpreter, for example).
For an EVAL-WHEN that is not a top-level form processed by

I'm not too opposed to :EXECUTE, :COMPILE and :LOAD as keywords, but don't
see the need for the extra verbosity of :COMPILE-TOPLEVEL or
:LOAD-TOPLEVEL. There are other ways to emphasize the "toplevel" aspect;
e.g., put ***WARNING*** in your reference manual.
