Importing unpick files would be useful for avoiding repetitions. The syntax would be similar to the one in Java.
Example:
bar.unpick in directory foo
unpick v4
group int some_type
org.example.Example.EXAMPLE
baz.unpick in the root directory
unpick v4
import foo.bar
target_method org.example.Example exampleMethod (I)V
return bar.some_type
OR
unpick v4
import static foo.bar.some_type
# or import static foo.bar.*
target_method org.example.Example exampleMethod (I)V
return some_type
