Idan Arye:
but I don't think Erlang's idiom of using maps as records is good for D.
I didn't meant to use that idiom in D, and I am not suggesting its usage in D. I wanted just to suggest an alternative way to modify associative array values that requires the keys to be already present. Because this is a common operation where you don't want to add a new key by mistake.
