Using Boost Regex for the first time I note that if there is an error in the syntax of the RE given then an exception is raised. Is this the only way of checking the RE syntax ? Or is there a function that I can call which can validate it for me without an exception. I don't see anything in the documentation (I'm using Boost 1.4 as I need to use it with Visual C++ 6).
