replace :: (Rx_ a a, ReplaceCase_ r a, Opt_ a) => [ReplaceCase] -> Pattern a -> r a -> Body a -> a

dynamic group replace

custom replacer fn returns replacement value. See defaultReplacer

>>> replacer::GroupReplacer String
    replacer = defaultReplacer 1 tweak1
          where tweak1 str1 = case str1 of
                                "101" -> "[сто один]"
                                "3" -> "[three]"
                                otherwise -> trace str1 "?"

Once vs All options

>>> replace [Once,Utf8] (Pattern "\\w=(\\d{1,3})") replacer $ Body "a=101 b=3 12"

"a=[сто один] b=3 12"

>>> replace [All,Utf8] (Pattern "\\w=(\\d{1,3})") replacer $ Body "a=101 b=3 12"

"a=[сто один] b=[three] 12"

static replace for simple (no group) needle
