Here is a revised proposal:
Keyword Default Meaning
:PACKAGE NIL NIL means use file's native package, non-NIL
is a package or name of package to load into.
:VERBOSE *LOAD-VERBOSE* T means print a message saying what file is
being loaded into which package.
:PRINT-FORMS NIL T means print forms as they are evaluated.
[Do we want this? It disappeared from the
latest Common Lisp manual.]
:ERROR T T means handle errors normally; NIL means that
a file-not-found error should return NIL
rather than signalling an error. LOAD returns
the pathname (or truename??) of the file it
T means update the pathname default
for LOAD from the argument, NIL means don't.
:STREAM NIL Non-NIL means this is an open stream to be
loaded from. (In the Lisp machine, the
:CHARACTERS message to the stream is used to
determine whether it contains text or binary.)
The pathname argument is presumed to be associated
with the stream, in systems where that information
The global variables' default values are implementation dependent, according
to local conventions, and may be set by particular users according to their
I left out keywords to allow using a different set of defaults from the normal
one and to allow explicit control over whether a text file or a binary file
is being loaded, since these don't really seem necessary. If we put them in,
the consistent names would be :DEFAULT-PATHNAME, :CHARACTERS, and :BINARY.
