the proposal is to specifically avoid having to be this repetitive

`Flags flags with Flags flags = ...`


This is way too much cognitive load only to get to the point of 
simply doing ``FOO | BAR | BAZ | QUX``


`with` when you think about using it, when you just want to use 
the enum it becomes cumbersome
