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
];
}
