Weird crash with (try ...).get(OrElse) in LambdaLift

[ochafik]

The following code snippet breaks the hell out of Scalaxy/Streams (symbol foo ends up not found in LambdaLift, despite seemingly having the proper owner chain):

val msg = {
  try {
    val foo = 10
    Some(foo)
  } catch {
    case ex: Throwable => None
  }
} get;
msg

It is currently mitigated by skipping any streams with a Try subtree, as detected by Strategies.hasKnownLimitationOrBug (see fe8531b), but a proper fix is needed to replace this broad hack.
