you can also do
if("key" !in root) {}
Additionally, just like associative arrays, if you need to access
the value, you can get a pointer to it with the in operator (and
if the key doesn't exist, it will return a null pointer).
const(JSONValue)* p = "key" in root;
if (p)
{
// key exists, do something with p or *p
}
else
{
// key does not exist
}
