Constant Vector as Argument in PPL

[NumericDavid]

OK, that's a valid point. The problem occurs on our Prime G2 Hardware and my Windows 11 64bit VC, both on 2023 04 13 (14730) but not on your VC (Mac).

I have a feeling that issue might be related to a CAS/ not CAS irritation. My application is purely numeric but normalize() seems to try to return an expression instead of numeric vector.
