SOME and Multiple Values
Is it reasonable to expect SOME to return multiple values? CLtL says:
"SOME returns as soon as any invocation of predicate returns a non-nil
value. SOME returns that value."
What if the predicate returns multiple values?
No, for the same reason that OR returns only a single value for clauses
other than the last one. That is, the implicit NULL test "consumes" the
values returned from the predicate, discarding all but the last one.
