Extra backslashes in nested json

[machadors]

There is an extra backslash when adding nested json.

This operations
json foo;
foo["key"] ="{\"hey\":\"hou\"}";
std::string result = foo.dump();

gives
result = "{\"key\":\"{\\\"hey\\\":\\\"hou\\\"}\"}"
with an extra backslashes in the nested json.

Is this a bug or there is another way to adding nested json ?

PD: This is my first ever github question, sorry in advance about format and so

You need to explicitly show json type like
foo["key"] = json::parse("{\"key\":\"hou\"}");

Yes, I have. Thanks for the help!
