问题
The containers package already contains functions to convert Set and List to Map but it's missing one for Vector from vector package.
Is this because package developers do not want to have dependencies on other (similar) packages?
Shouldn't be some general package which converts between data structures? In this way I always have to convert to List to convert to other structures. But I want to minimize use because of performance.
