+@itemize
+@item Be an 'unopinionated' toolbox that provides useful utilities without
+      debating which is better or why
+@item Remain free of external gem dependencies
+@item Stay true to the spirit of the languages providing inspiration
+@item But implement in a way that makes sense for Ruby
+@item Keep the semantics as idiomatic Ruby as possible
+@item Support features that make sense in Ruby
+@item Exclude features that don't make sense in Ruby
+@item Be small, lean, and loosely coupled
+@item Thread-safety
+@item Backward compatibility
+@end itemize")
