More permissive license?

Hi there!

This project is licensed GPLv3, which kinda makes things a bit odd for others looking to it for inspiration. Is there any potential to use Apache License or something a bit more permissive? The use case I've specifically heard is if for some reason someone wanted to use a line from a groovy script, technically their new script must be licensed GPLv3 as well.

Cheers,
Jeffry
