According to this

this is correct static initialization for AA:

That only works inside a function, and, ironically, only if the 
variable is not `static`...

I believe this is technically an implementation shortcoming - it 
is supposed to work in a static context too, but it isn't 
implemented. But regardless, right now, you need to do it in a 
function (or a static constructor) right now.

You can separate declaration from initialization on module-level 
like so:

immutable RoundingMode[string] ibmRounding;
shared static this() {
  ibmRounding =
  [
     ">" : RoundingMode.towardPositive,
     "<" : RoundingMode.towardNegative,
     "0" : RoundingMode.towardZero,
     "=0": RoundingMode.tiesToEven,
     "=^": RoundingMode.tiesToAway
  ];
}
