ConditionalType enum Null safety

Controls characteristics about Case blocks.

The default type is none. The unique and priority values have behavior similar to what is implemented in SystemVerilog.

priority indicates that the decisions must be executed in the same order that they are listed, and that every legal scenario is included. An exception will be thrown if there is no match to a scenario.

unique indicates that for a given expression, only one item will match. If multiple items match the expression, an exception will be thrown. If there is no match and no default item, an exception will also be thrown.
