Zip multiple sequences

Question

I am trying to zip multiple sequences to form a long tuple:

val ints = List(1,2,3)
val chars = List(\'a\', \'b\', \'c\')
val strings = List(\"Al         


        

Answer 1

Using product-collections

scala> ints flatZip chars flatZip strings flatZip bools
res0: org.catch22.collections.immutable.CollSeq4[Int,Char,String,Boolean] = 
CollSeq((1,a,Alpha,true),
        (2,b,Beta,false),
        (3,c,Gamma,false))

This currently works for arity 1 - 22. As you can see the types are preserved.
