as to in returning null, that is what 'in' does with AA's; if the key is in the
AA return a pointer to the value, otherwise, return null.

In fact, the code I wrote works the same as 'in' for AA's

The usual way to use the return from 'in' where it might give null is this:

if(auto v = i in j)
{
  use(*v);
}
else
{
  // i not in j
}
