.test domain in URL package

[bantya]

The RFC dictates the reserved TLDs for web development and testing.
These are:
.test
.example
.invalid
.localhost

The problem is these TLDs re not supported by URL package. Having these working with URL package will be a huge relief for web-devs like me.
Thanks
