By both I understand "join as in Python". Right?

Question is, where to stop?

1. string only (i.e. leave as is)

2. const(char)[] only (to allow joining char[] values)

3. various width of char, i.e. why shouldn't you join an array of wstring?

 From 3, the incremental effort to generalize to any type is virtually 
nonexistent, and the effort to generalize to ranges instead of arrays is 
minor. To me these are positives.
