How Does Regex Fit with the Standard Library?
There is currently no support for regular expressions in the C++ Standard Library. This is unfortunate, as there are numerous uses for regular expressions, and users are sometimes deterred from using C++ for writing applications that need support for regular expressions. Boost.Regex fills that void in the standard, and it has been proposed for inclusion in a future version of the C++ Standard. Boost.Regex has been accepted for the upcoming Library Technical Report.
