OK, u saw implementation for classes with 2 colons
class Derived : some.module:Base {
its simple sample but can be more difficult that uses colon too.
     at here 1st colon means inheritance

u can implement it as
class Derived : some.module at Base { // @
i dont care
but "inplace import with using" looks more preferably
