import std.range; import std.array; import std.conv; import std.algorithm; import std.string; import std.stdio; enum Instructions: ushort { add = 123, sub = 124, } uint[ushort.max] inst; void initInst() { //Removing this line drastically reduces compile time alias InstElem = ElementType!(typeof(inst)); } void main() { }

Reduced: alias R = uint[ushort.max]; void front(T)(T[] a) {} void main() {front(R.init);}
