Yes I know, I wrote this thing (before me Smalltalk was not mentionned).<br>

Maybe it was a bit late at night ;) , anyway I had not so many choices:<br>

I don't like that implementation. To me it's overengineered and unintuitive. The following is enough for most of cases IMHO:<br>
<br>
Collection >> join: delimiter<br>
<br>
^String streamContents: [ :stream |<br>
self<br>
do: [ :each | each putOn: stream ]<br>
separatedBy: [ delimiter putOn: stream ] ]<br></blockquote><div><br></div><div>Actually, thinking a little, why not</div><div><br></div><div><span class="Apple-style-span" style="font-family: arial, sans-serif; font-size: 13px; border-collapse: collapse; "><br>

This reflects my preference (receiver is the collection, argument is the delimiter) and is not compatible with Pharo's implementation.<div class="im"><br>

- use String streamContents: [:stream | arrayOfStrings do:<br>
[:eachString | stream nextPutAll: eachString] separatedBy: [stream<br>

I would have written this form in Smalltalk, however I find the<br>
periphrase a bit long versus other languages<br>

I see you updated the page, and yes, the phrase is pretty long compared to other languages'.<div class="im"><br>

- use reduce: to find a shorter form comprehensible by foreign<br>

#reduce: combined with #, may give the impression to outsiders that strings have dynamic implementation (like in C++).<br><font color="#888888">

Of course, it would also be nice to see a Xtreams solution.<br>
