Hi,

What is the best strategy to handle spaces with X3?
The files I want to parse have sometimes spaces or tabs for separators, but
I also need to scan number that have an attached suffix (so x3::double_ >>
*x3::char_).
If now I want to parse groups of strings, starting with a rule like
const auto pin = x3::rule<class pin, std::string>()

  = x3::alpha >> *x3::char_;
what is the best to create a vector of these? *pin or pin % ' ' and will
the latter also handle tabs by default?

Cheers,

Matthieu
