If Emacs gained a 'set-arg' function (similar to 'setarg1' in your
message) that does the right thing, you could say:
--apply set-arg args arg -- --eval '(some-func 1 (car args) t)'
Another way would be a function that "intelligently" converts arguments
to other types. This is similar to how Eshell command forms work: if
you're calling a Lisp function with sh-like syntax, it will
automatically convert arguments that look like numbers into actual
numbers. So maybe you could do something like:
--apply autoconvert-strings-and-apply some-func 1 arg t
That seems clumsier to me than 'set-arg', but since these could all be
written as Lisp functions, users or package authors should be able to do
whatever they need. Of course, core Emacs could add whichever helper
function(s) seem generally useful.

Yeah, for more-complex forms, you'd still need to fall back to --eval or
something similar. But a Lisp function like 'set-arg' could let us reuse
the --apply machinery. I think it could be as simple as this:
(defun set-arg (name &rest value)
(set (intern name) value))
That should give us '--set', except that it's spelled '--apply set-arg'.
