I'm reminded of placeholders in PostgreSQL; the type is needed to choose
overloaded functions and operators, so this doesn't compile (without
extra metadata):
Select do_something(?) as result
Instead, you can insert a dummy cast to indicate the type:
Select do_something(?::int) as result
The PHP equivalent would be something like this:
$f = (DateTimeImmutable)?->format('c');
Or, slightly more readable but less consistent with casts:
$f = (? as DateTimeImmutable)->format('c');
That doesn't solve the second part of the problem though:

I thought I'd throw it out there anyway in case it stimulates any other
ideas.
