Odd string concatenation in ruby, feature or bug?

We just got stung by an apparent 'feature' in ruby where if you put 2 strings side by side they are automatically concatenated together, i.e.:

irb(main):001:0> ['h1', 'h2' 'h3']
=> ["h1", "h2h3"]

Why would this not throw an error? It seems surprising.

This is documented in the Ruby official [string literal docs](http://ruby-doc.org/core-2.2.1/doc/syntax/literals_rdoc.html#label-Strings) – infused Apr 23 '15 at 16:43
