Under Andy's proposal, the declaration about would duplicate the last
declaration in the list, based on a title collision.

However, this does require an act of intention on the part of the user to
set "name" to a value that is different from "title". Is there a major risk
of accidentally creating duplicate resources? Would the resulting catalog
fail in a way that obscured the source of the problem?
To me, this proposal seams like the most pragmatic way to alleviate the
problem without a major retool of how the Package type works. At the
moment, I'm not convinced that opening up the possibility of accidental
misuse outweighs the current issues surrounding the workarounds people have
to use in order to install a package and a gem that happen to share the
same name.
