I have a Seq containing objects of a class that looks like this:
class A (val key: Int, ...)
Now I want to convert this Seq to a Map, using the key value of each object as the key, and the object itself as the value. So:
val seq: Seq[A] = ...
val map: Map[Int, A] = ... // How to convert seq to map?
How can I does this efficiently and in an elegant way in Scala 2.8?
