And it does it in a way that PRINT-OBJECT and other things that may want
to know a function's canonical name (CL:FUNCTION-LAMBDA-EXPRESSION) can use.

There are some fairy obscure cases where the two-arg CCL::LFUN-NAME isn't
GC-safe, and I have the feeling that it would create more confusion if I were
to try to enumerate those cases than it would to remain silent.   The particular
case that Ron was asking about - where he wants to give an otherwise anomymous
function a name - should always be GC-safe.
