[Boost-users] Regex question: is this a bug or a feature?

My pattern matching was failing when I had these definitions, which I 
happen to prefer:

const string number = "[0-9]+";
const string name   = "[A-z][A-z0-9]*";

("name" is supposed to match a typical variable name)

The program is working fine now, after I am using these ones:

const string number = "\\d+";
const string name   = "[A-z]\\w*";

The only difference that I aware of, is that the second form accepts 
underscores as part of variable names.

TIA,
