NoMethodError: undefined method `then' for ^http(?:s)?://((?:\w)+):Hexpress

any idea what I'm doing wrong here?

Oops. Needed to require the web library.
`require "hexpress/web"``

[EDIT]
need to require verbal_expression
require 'verbal_expression'

See below

You're doing nothing wrong, it's only that I've moved then to the
VerbalExpression spec. See, VerExp uses Then where we use With. With
require 'verbal_expression' we match the verbal expression spec.

The reason I've removed then from the default hexpress method list is
because it's also a ruby keyword and I'd like to avoid confusion.
