This might be a typo in your example but why should it be a
compile-time error, it cannot know if the key already exists in
compile time on a variable. First time initialization should
always work anyway.
Because opIndexAssign cannot distinguish at compile time between
initialization and assignment:
```d
Stuff[Key] aa;
aa[key] = Stuff(args); // ostensibly, initialization
aa[key] = otherStuff; // assignment to existing value
```
Same syntax, different behavior. This can only be caught at
runtime. `require` and `update` though should be able to pull
this off, and that they don't is a bug.
