Thanks.

I don't like that implementation. To me it's overengineered and 
unintuitive. The following is enough for most of cases IMHO:

Collection >> join: delimiter

 	^String streamContents: [ :stream |
 		self
 			do: [ :each | each putOn: stream ]
 			separatedBy: [ delimiter putOn: stream ] ]

This reflects my preference (receiver is the collection, argument is the 
delimiter) and is not compatible with Pharo's implementation.

I see you updated the page, and yes, the phrase is pretty long compared to 
other languages'.

#reduce: combined with #, may give the impression to outsiders that 
strings have dynamic implementation (like in C++).
