Much better than naming conventions, in 2.0 you can declare the type of the
parameter. This should be a mandatory coding standard: it's really useful
documentation, and it also catches a great number of silly coding mistakes.

See http://www.stylusstudio.com/schema_aware.html - though this technique is
useful even without a schema, and works for template parameters as well as
function parameters.
