re-use of tester results in incorrect output

[wwwouter]

verbalExpr = require("verbal-expressions")

endOfOutputTester = verbalExpr()
      .startOfLine()
      .then("www")

test1 = "www"
console.log(endOfOutputTester.test(test1))
console.log(endOfOutputTester.test(test1))
console.log(endOfOutputTester.test(test1))
console.log(endOfOutputTester.test(test1))
console.log(endOfOutputTester.test(test1))

the output is

true
false
true
false
true

using version 0.1.0

I did a bit of research and found that this is not caused by this library it's a bug in the regex engine:

For your particular example removing the g modifier would fix the problem

var reg = VerEx().startOfLine().then("www").removeModifier("g");
