In that case APropValue will be a reference to a Object. I trust
reference to objects on a 64-bit system is a 64-bit integer? And on
32-bit systems they will be a 32-bit integer.

It is one function that can handle various data types. To not use
variants, I would have to create stacks of overloaded functions all
with pretty much the same implementation - that's lots of code
duplication. For now that function works 100% and has been unit tested
- so I feel pretty confident that in this case variants are doing
their job correctly.
