Q: Why does it work with enums?

e.g., If I create a type foo_t as enum (...) and install the function
foo_text on foo_t the gist works. Why would the presence of a text
verison of the composite not get used the same way?

If the function works I'm happy, I just don't see the reasoning
behind having the enum's supported automatically and the composite
not handled.
