better way to wrap scala region with brackets

[fommil]

This isn't necessarily a scala-mode idea, perhaps it belongs in our Hacks page.

I often find myself with some code like

val foo = bar.doTheThing(baz)

and I want to rewrite it as

val foo = magicalWowzers {
  bar.doTheThing(baz)
}

but doing so is really clunky. It would be great to have a key binding such that one only needs to move the point to the beginning of bar (i.e. to end of line, or select a region) and do this automatically.

Oh, I solved this already with smartparens.
