When writing type-level code (and to a lesser extend always) complex types tend to accrue a lot of constant prefixes. Could the compiler, when reporting errors, at reaching a certain threshold (type length as a string, number of referenced types/number of types from a single package, number of occurrences of the same type - to be decided) add import clauses before/after the error report, and reference the types in the report through those imports? This would immensly improve the readability of the report. In many cases, this would only add a single line, as a great chunk of all code deals with classes from the same package which could be imported together with the brace syntax.
What is the view of movers and shakers on this feature? Does it look like a possible first issue? If such a change would be welcome and someone pointed me in the right direction, I could perhpaps give it a go.
