Subject: Change the semantic of the last template parameter of Assignment from
 "Scalar" to "SFINAE" only. The previous "Scalar" semantic was obsolete since
 we allow for different scalar types in the source and destination
 expressions. On can still specialize on scalar types through SFINAE and/or
 assignment functor.
