When things are fairly small, it isn't an issue and certainly documentation is
key. I'm just very OCD about conventions and naming and I like having things
named in ways that it is explicit to the purpose. Generally, it is fairly easy
to tell that ssh::files would most likely be a class that deals with the files
associated with setting up ssh and not some variation of how ssh is setup.
But, in general, when I see foo::bar, I assume bar is a subclass (ergo
derivative of) foo. But since both fragments and subclasses are useful in
Puppet, for those that so feel inclined (and I think the Puppet community has
expressed interest in consistent style and practice guides to grow the
community closer), I think a naming convention to differentiate is valuable,
even if just for us OCD folks. :)

I guess I could see this if the classes were scattered throughout /manifests/.
I approach module building the same way in terms of breaking the classes
into smaller pieces. I guess I don't see a specific need for a
fragment designation.
I usually create a class named "foo" in init.pp and include the sub
classes there:
class files {
# include files class groups
include files::all
include files::rhel5
# include files class hosts
include files::host1
}
In site.pp I just "include foo." I document all this in the README
and comment the init.pp file. It just seems natural to me that way.
My setup isn't probably as complex as some so maybe I'm missing
something......
