`_` here is part of the `Declaration_` name, not a pattern of its own. `Declaration_` is an enum variant that used to be called `Declaration`, but had to be renamed relatively recently when variants started taking up a name in the type namespace, to avoid colliding with the `Declaration` struct.

as if `item` matches the result of any function starting with Declaration and with any suffix
In patterns, the syntax `Foo(..)` indicates enum variants or tuple-like structs, not arbitrary functions.
I can't seem to find where Declaration is defined, where `mportant` comes from
As Josh mentioned, the rustdoc documentation for Servo, all its dependencies, and the Rust version we’re using is at http://doc.servo.org/ . They can be search with the bar at the top, or with an URL like http://doc.servo.org/servo/?search=foo
