OK, I made up the example so the OP would understand
the brackets, that is, the first (outer) pair makes it
a class, and the second (inner) pair puts some chars
into that class. So you'd not think [[:alnum:]] is
"atomic" syntax... I don't know how to better explain
it - the example is more clear, but of course examples
should make sense as well...
