Semigroup |+| is 4 times slower than scalaz Semigroup |+|, when combining two large Maps that have nested Maps inside.

Map type: Map[Seq[Char], Map[Char, Int]]

Thanks for reporting this, @rayqiu. I think this is a duplicate of #1290, so I'm going to close it out. @rayqiu please feel free to reopen it if you have an example of another data type that is also slow with |+|.
