+/// Represents a proc or verb path.

+/// Despite having no DM-defined static type, proc paths have some variables,
+/// listed below. These are not modifiable, but for a given procpath P,
+/// `new P(null, "Name", "Desc")` can be used to create a new procpath with the
+/// same code but new `name` and `desc` values. The other variables cannot be
+/// changed in this way.
+///
+/// This type exists only to act as an annotation, providing reasonable static
+/// typing for procpaths. Previously, types like `/atom/verb` were used, with
+/// the `name` and `desc` vars of `/atom` thus being accessible. Proc and verb
+/// paths will fail `istype` and `ispath` checks against `/procpath`.
