// same as assert ("cheesecheese" =~ "cheese").find()

assert "cheesecheese" =~ "cheese"

// lets create a regex Pattern

pattern = ~"a*b"

assert pattern instanceof Pattern

assert pattern.matcher("aaaab").matches()

// lets create a Matcher

matcher = "cheesecheese" =~ "cheese"

assert matcher instanceof Matcher

answer = matcher.replaceAll("edam")

assert answer == "edamedam"

assert ("aaaab" =~ "a*b").matches()
