Filters for parameter assignment

[lars-reimann]

Is your feature request related to a problem? Please describe

The implicit self parameter cannot be annotated. However, there is no filter to hide them.

Desired solution

A new filter is:implicit. We could also add more variant for the four different ways to assign parameters:

• is:implicit
• is:nameOnly
• is:positionOnly
• is:positionOrName

For modules, classes, functions the filters should return false.
