Concrete methods

def apply(mod: A => A): S

An alias for using. Explicit calls to using are preferred over this alias, but quicklens provides this option because code auto-formatters (like scalafmt) will generally not keep modify/using pairs on the same line, leading to code like

An alias for using. Explicit calls to using are preferred over this alias, but quicklens provides this option because code auto-formatters (like scalafmt) will generally not keep modify/using pairs on the same line, leading to code like

x
 .modify(_.foo)
 .using(newFoo :: _)
 .modify(_.bar)
 .using(_ + newBar)

When using apply, scalafmt will allow

x
 .modify(_.foo)(newFoo :: _)
 .modify(_.bar)(_ + newBar)
