<|(_:_:)
public func <| <A, B>(lhs: (A) -> B, rhs: A) -> B
Application operator. This operator is redundant, since ordinary
application f(x)
means the same as f <| x
. However, <|
has low,
right-associative binding precedence, so it sometimes allows parentheses to
be omitted; for example:
f <| g <| h(x) = f(g(h(x)))
It is also useful in higher-order situations, such as zipWith(<|, fs, xs).
