Without going into the full context of what you're doing, the answer to your
final question is pretty straightforward.
The whole compile process has a list of known resource types (which includes
nodes, classes, and definitions), available via Environment:
Puppet::Node::Environment.new.known_resource_types.hostclasses
Scopes just give you a search path for unqualified types/etc, which you won't
need in your case. So, you can just ask for the type directly.
Note that each type (node, definition, hostclass) has multiple methods:
hostclass(name) # finds an existing class
find_hostclass(name) # loads a class into memory if it's not there
hostclasses # return all known hostclasses. or maybe just names?
There are similar methods for the other types. You can look through
lib/puppet/resource/type_collection.rb for the available methods (an instance
of this is what's available at Environment.new.known_resource_types.
