Description

Sometimes it would be helpful to convert between an early-exit if statement and a guard statement, either to better express the semantics of early-exit, or the code block within the early-exit statement has become overly long.

e.g. convert between

if let a {
  // code block A
  return a
}
// code block B
return b

and

guard let a else {
  // code block B
  return b
}
// code block A
return a
