Is it possible to add items to the arrays and hashes at compile time?

[Dennis Ritchie via Digitalmars-d-learn]

Does D the ability to add items to arrays and hashes at compile 
time?

For example, how do I do it in compile time?:

int[][int][int] hash;

hash[4][6] ~= [34, 65];
hash[5][7] ~= [4, 78, 21];
