I think you missed my point: I don't want the options list at the front
because I'm afraid it will prevent us from making good extensions in the
future. Offering both syntaxes does not fix that.

Well, there was some discussion of having a "bulk check" or wildcard
capability in the CHECK command, but this seems like an awfully
constricted version of that.
The thing I'd prefer to see in the first cut is some notation for "check
all functions owned by me that are in language FOO". The reason for the
language restriction is that if we think the options are
language-specific, there's no reason to believe that different
validators would accept the same options.
