Yeah it is not ideal. This trick can also shield you in case if 
multiple elements from static foreach matches inner static if, 
just by adding a check to it if this enum was defined earlier. 
Also beware of code blocks for foreach or inner static if, since 
it will limit enum declaration to that block and wont be 
available to static if defined outside of foreach (the one for 
default return).
