No, I don't think so.

As Kevin pointed out, there's not enough new going on here to deserve a
fancy new (scary) name. We're taking a stream of T values and *map*ping
each one to zero or more U instances and putting them *into* a U consumer.
In the general case, it's not really flattening (or exploding), even though
what I would describe in those terms is a special case of this.

FlatMapper is a *synecdoche*, a more specific term standing in for a more
general concept, and if it makes Scala devotees happy, then I guess it does
no harm. But (and I know it must seem like I'm reversing myself, since I
suggested "flattenInto") I don't see a need to repeat the favor in the
method name.
