Sample, tested on 2.061alpha:

enum Command{
    Char,
    Any,
};

bool test(Command cmd)
{
    //if with(Command) removed and Any --> Command.Any it works
    switch(cmd) with(Command)
    {
    case Any:
        return true;
    default:
        return false;
    }
}

enum x = test(Command.Any);

Assertion failure: '!istate->start' on line 1122 in file 'interpret.c'


If I swap switch(cmd) with(Command) to with(Command) switch(cmd) it gives:

ctfe_ice.d(8): Error: Cannot interpret Command at compile time
ctfe_ice.d(17):        called from here: test(cast(Command)1)

Fix issue 9236 CTFE ice on switch + with(EnumType)

When it's with(Type), dont try to interpret it, it's a no-op.
