Hi @cbrunnkvist! Thanks for creating this set of issues! They're super helpful in fixing bugs in the mutant-placing code! I've fixed the previous two unplaceable mutant issues, but this one seems to be a little more tricky. I won't work on this any time soon as I think the way to fix this would be a bigger rework of the mutant searching and replacing logic. At the very least after 0.10.0.

For future reference, a reproduceable smaller code example:

serviceProvider
  .request { _ => "foo" }
  .getOrElse("bar")
