[Python-ideas] Dict literal use for custom dict classes

[Jelte Fennema]

This is indeed another option, but it decouples the keys from the values.
Which makes it harder to see with a quick look what key will have what
value, you will have to count the keys. This feels to me like a serious
drawback of this method since knowing what value a key will have is pretty
important when talking about initializing dictionaries.
