but it's true !
There's **nothing** to check the availability of a Key. At least I would
expect opIndex[string key] to return a JSONValue with .type ==
JSON_TYPE.NULL, but no...
Also If it was returning a JSONValue* it would be easyer to check if a
key is present.
God damn it, how could you miss this design flaw when std.json was
reviewed ?!
JSONValue supports `in`, though:
----
import std.stdio;
import std.json;
void main()
{
foreach (jsonStr; ["{}", "{\"foo\": 42}"])
{
JSONValue jsonObj = parseJSON(jsonStr);
const JSONValue* p = "foo" in jsonObj;
if (p is null) writeln("not found");
else writeln(*p);
}
}
----
Looks like documentation has been neglected.
