Vector API Mask Boolean Operation Support

[Viswanathan, Sandhya]

Hi Paul,

Having species specific classes for Mask would be very helpful both from the Mask operation support and Mask boxing point of view.

Best Regards,
Sandhya

I presume the binary ops need to check that the species is the same?

Do you require that we explicitly transform GenericMask into a bunch of species specific classes to optimize the detection of the species? That’s easy to do with the template infrastructure.

An alternative strategy that might help is to annotate the species field with @Stable.
