Pascal simply is a strongly typed language. Vector intrinsics are no
reason to weaken this. Thus you need to declare operator overloads that
hide the nitty, gritty details of assigning a TVector4 to a __m128, e.g.:
type
TVector4 = packed record
X, Y, Z, W: Single;
class operator := (const aArg: TVector4): __m128;
class operator := (const aArg: __m128): TVector4;
end;

That's true - I'm still learning when an implicit typecast is valid and
when it isn't. In the above example, __m128(some_TVector4_type), is
usually valid because the alignments and memory are the same.
Internally though, the __m128 types are broken in a few places.
