Re: Sbcl feature - symbol occuring at toplevel is not reported with warning

Hi there!
Darcs marks conflicts in a file with

but sbcl compiles such a file without warning. Is it ok?

E.g. lispworks warn that "variable assumed special"

In fact, it seem to be a bug, as

v

would lead to evaluation of v at load time, wouldn't it?
And v is an unbound variable.

Ten warnings is not quite "without warning." Interestingly, though,
the resulting test.fasl loads just fine, although loading test.lisp
directly hits an error on the first v.
