Description

Alias TypeClass in BinaryScalar and LargeBinaryScalar are being BinaryScalar and LargeBinaryScalar. Are they supposed to be BinaryType and LargeBinaryType?

I'm having issues when I use TypeTrait on ScalarType::TypeClass - compiler complains that there are no whatever members in specialized TypeTrait<BinaryScalar> and TypeTrait<LargeBinaryScalar>.
