Another approach would indeed be (as you say in the other mail) to add
support for telling PyPy explicitly that some list can contain only
instances of a specific class and (more importantly) that a class is not
to be considered to be "dynamic" meaning that its fields are fixed and
of specific types. So far, we have not really gone in such directions,
because that is language design and we leave that to the CPython devs
;-).
Hmmm, how about dataclasses ;-) Maybe those can be used as optimization
targets under some reasonable assumptions:
@dataclass
class Point3D:
x: float
y: float
z: float
Feels pythonic much to me...
