It's what we call a constant pattern. The syntax is still in flux. 

Given that a switch on an enum does not require the class of the enum constant to be specified, another possible syntax may be case R(a), 
or we may want a quoting mechanism for the constants, case R('E.a) or case R(== E.a). 

Anyway, you can already write case R(E e) when e == E.a.
