I am having a lot of trouble understanding the intended meaning of "#," in
compiled code. I find it hard to believe that it is really intended to be
like "#.", as the manual implies. In particular, the result of "#." in a form
becomes PART OF the form. Thus, for example, you can do (DEFMACRO FOO
#.(MUMBLE) ...) and the result of invoking MUMBLE is used as the parameter
list to DEFMACRO. Similarly, if I say (SETQ X #.(MUMBLE)) and MUMBLE returns
a list, then the list will be evaluated. Is the intent that "#," can be used
this way (in compiled code), or can it be used only within quoted structures?
Implementors: How have you implemented "#,"? Are there are restrictions on its
use? If so, can they be stated clearly?
