This fails to parse, with System.FormatException: Input string was not in a correct format being thrown:

MathParser parser = new MathParser();

parser.Operators.Add("λ", (left, right) => Math.Pow(left, right));

Assert.AreEqual(Math.Pow(3, 2), parser.Parse("3λ2"));

However, if the last statement is changed to have whitespace in the expression, it parses correctly:

Assert.AreEqual(Math.Pow(3, 2), parser.Parse("3 λ 2"));
