Description bearophile_hugs 2011-02-07 14:32:50 UTC 
This is Python 2.6.6 code (shell):

>>> "x".join("123")
'1x2x3'


This is handy in several situations. So I'd like std.string.join() to join chars in a similar way:

join("123", "x") ==> "1x2x3"

In Python and Haskell:

>>> s = "language"
>>> "|".join(s)
'l|a|n|g|u|a|g|e'


Prelude> intersperse '|' s
Prelude Data.List> intersperse '|' s
"l|a|n|g|u|a|g|e"

They are different requests.
Comment 4 Jack Stouffer 2016-04-11 22:40:31 UTC 
This is a one liner,

    string input = "123";
    auto result = input.roundRobin('x'.repeat(input.length - 1));

Going off of Walter's comments in this PR, https://github.com/D-Programming-Language/phobos/pull/4153, I am marking this as WONTFIX.
