Improvement maybe: Fill any object you want.

[didslm]

Summary

I already did something in my project where it uses faker to fill objects and tries to guess the format if not it goes by the input type (int|string|bool) it works even with custom object.
There is already something inside for Doctrine entities but I couldn't find it for objects with some setters.
Btw this works only if the object has setters.

Self-enclosed code snippet for reproduction

To use it you just provide the object and it will fill it.
Example

$faker->fillObject($someObject, FILL_OPTIONAL_PARAMETERS);
