joinTo

fun <E : Any, A : Appendable> EntitySequence<E, *>.joinTo(    buffer: A,     separator: CharSequence = ", ",     prefix: CharSequence = "",     postfix: CharSequence = "",     limit: Int = -1,     truncated: CharSequence = "...",     transform: (E) -> CharSequence? = null): A(source)

Append the string from all the elements separated using separator and using the given prefix and postfix.

If the collection could be huge, you can specify a non-negative value of limit, in which case only the first limit elements will be appended, followed by the truncated string (which defaults to "...").

The operation is terminal.
