Hm, I got next error on this code

void main()

immutable s = ["red", "blue"];

This works:
auto s = ["red", "blue"];
auto js = s.join("");
2 issues in your snippet:
1) need to define separator for join
2) fully immutable array can't act is InputRange as one can't
popFront from it
Arguably join should have made constraint check on tail-qualified
copy of s instead though (as it is legal to copy imutable(char[])
into immutable(char)[]). I bet there is even bugzilla entry for
it :)
