You're welcome.
Hopefully, reading and understanding the code posted here (not just
mine) will both get you a better grasp of the various ways these kinds
of things can be tackled using HOFs like ma

Eh -- filter identity doesn't retain false:

cant seem to find a solution other than using loop-recur. then i read
somewhere almost all loop recur situations can be translated into
