If that works out, we are able to also lint Fluid Templates and check ViewHelper Usages. If an argument has changed, we can rename it or warn about that.

Also we would be able to adjust the namespace imports, as Tx_ would be namespaces.

If that works, we need to create further issues:

• Migrate namespace imports, in both syntax versions.
• Check deprecated / changed arguments of ViewHelpers.
• Check deprecated / changed ViewHelpers (sometimes the namespace of a ViewHelper or the name changes)
