I’d ask you to get back to “use” keyword, despite of it’s in use in Laravel or
somewhere else.
As a developer I cannot even imagine what “use” could mean in web frameworks
context, I hope it could have a better name and at the same time we can advise
to use namespaces if you don’t want to get something broken after upgrading
language.
Just my 5 cents.
