some every notany
remove-if delete-if
Those are useful operations, and I would like to add facilities to do
them. However, I don't like the CL functions because of their CL
style keyword argument, which I feel conflicts with the spirit of
Emacs Lisp.
Thus, I would rather add other facilities with simpler interfaces
to do these things.
Instead of `remove-if', there could be a macro `filter',
like `dolist' except that the body says whether to keep
an element or discard it.
Another macro could be designed to replace `some', `every' and
`notany'.
These macros would also run faster than those function calls,
for whatever that is worth.
