Description Louis Rose CLA 2011-03-05 14:29:29 EST 
I've been using a Collection#join method for a lot of EGL templates, and I think it's time to promote it to a built-in method in EOL:

var s = Sequence{'foo','bar','baz'}

s.join() -> 'foobarbaz'
s.join('-') -> 'foo-bar-baz'

Collection#join(pattern) is the inverse of String#split(pattern)
Comment 1 Louis Rose CLA 2011-03-05 14:41:41 EST 
I've added join to CollectionOperationContributor, added some tests to CollectionTests and updated the Epsilon book.

Assigning to Dimitris for build integration; thanks!
Comment 2 Louis Rose CLA 2011-03-17 11:17:28 EDT 
In fact, there is already a concat operator that is equivalent to join/1.

I've removed join/0 and join/1 and added concat/0.
