class Sexp::Pattern

Matches any atom who’s string representation matches the patterns passed in.

examples:

s(:a) / s{ m('a') }                                      #=> [s(:a)]
s(:a) / s{ m(/\w/,/\d/) }                                #=> [s(:a)]
s(:tests, s(s(:test_a), s(:test_b))) / s{ m(/test_\w/) } #=> [s(:test_a),

TODO: maybe don’t require non-sexps? This does respond to =~ now.
