Fallback

Syntactic sugar for Swift do-try-catch.

At a Glance

value = try fallback(
  try get("A"),
  try get("B"),
  try get("C"),
  try get("D")
)

is equivalent to:

do {
  value = try get("A")
} catch {
  do {
    value = try get("B")
  } catch {
    do {
      value = try get("C")
    } catch {
      value = try get("D")
    }
  }
}
