Error on ColorTypes

[bertschi]

In my library I use Cassette for function tracing and have encountered some errors. Have boiled it down to a minimal example:

using Cassette, ColorTypes
Cassette.@context Ctx

Base.typename(RGBA)  # works without issues
Cassette.overdub(Ctx(), Base.typename, RGBA)

The last call fails with the following stack trace

ERROR: type DataType has no field body

Guess that this is an issue in Cassette ... any ideas?
