Bug 238 – Cannot initialise const field from foreach loop on associative array

This is a bit confusing. The code explains it best: -- class Confectionary { this(int sugar) { //if (sugar < 500) // tastiness = 200; //for (int i = 0; i < 10; ++i) // tastiness = 300; //int[] tastinesses_array; //foreach (n; tastinesses_array) // tastiness = n; int[int] tastinesses_aa; foreach (n; tastinesses_aa) tastiness = n; } const int tastiness; } -- All the commented-out cases are acceptable ways of initialising the const member, tastiness. However, DMD issues an error "can only initialize const tastiness inside constructor" for the last foreach loop. This can be circumvented by putting the loop in a function which returns the value to be assigned to the field, but it's still an annoyance.

Fixed in DMD 0.178.
