A WriteStream is usually a good way to do this, something like this:
| ws |
ws := WriteStream on: ''.
'A series of words to be shuffled' substrings shuffled
do: [:e | ws nextPutAll: e; nextPut: Character space].
ws contents allButLast
But you can also iterate over a collection and accumulate the results
using #inject:into:, for example like this:
'A series of words to be shuffled' substrings shuffled
inject: nil
into: [:str :e | (str ifNil: [''] ifNotNil: [str, ' ']), e]
or this:
('A series of words to be shuffled' substrings shuffled
inject: ''
into: [:str :e | str, ' ', e]) allButFirst
