2.01 Create a CollSeq

Create a CollSeq

Let the compiler infer the appropriate implementation:

scala> CollSeq(("A",2,3.1),("B",3,4.0),("C",4,5.2))
res1: com.github.marklister.collections.immutable.CollSeq3[String,Int,Double] = 
CollSeq((A,2,3.1),
        (B,3,4.0),
        (C,4,5.2))

Notice that the correct types are inferred for each column. Consistent tuple length is guaranteed by the compiler. You can't have a CollSeq comprising mixed Product2 and Product3 types for example.
