  @item{a @deftech{quantified pattern}: a @tech{pattern} followed by either @litchar{*} (``zero or more''), @litchar{?} (``zero or one''), or @litchar{+} (``one or more''). Quantification can also be denoted by integers within curly brackets. So @litchar|{{2}}| means ``exactly 2''; @litchar|{{2,5}}| means ``between 2 and 5, inclusive''; @litchar|{{2,}}| means ``2 or more''; and @litchar|{{,5}}| means ``up to 5''.}
