In D, all variables are initialised to the .init value for their
type when declared. If a is a
Thank you for reply.
Here is what i trying to achieve, i have module-wise data
structure, which should exist in form of array and associative
array, but i can't calculate second form on compile time:
const a = [[a,1],[b, 2], ... ];
const string[string] b = a.map!(...).assocArray;
This is

}
}
It might not be entirely appropriate
