I've seen this before, but why is it preferable to this?

  A.f2 := B.f2

There's an article on comp.lang.ml where Xavier Leroy mentions this
syntax as a way to get module initialization code to run ... but I get
the impression that folks are using it when it's semantically
equivalent to the same thing with the "let _ = " omitted entirely.
