- The :func:`.cast` function, when given a plain literal value,
will now apply the given type to the given literal value on the
bind parameter side according
to the type given to the cast. This essentially replaces what would
normally be the detected type of the literal value. This only
takes effect if the auto-detected type of the literal value is either
"nulltype" (e.g. couldn't detect)
or a type that is of the same "affinity" as the cast type.
The net change here is that the :func:`.cast` function includes more
of the functionality already present in the :func:`.type_coerce` function.
