This limitation is because function body dumping is not supported.
Default values can be almost arbitrary expressions.  Dumping of
expressions is not supported.  It can be added, but I have no time to do
it.  Contact me privately if you want help adding it yourself.

You might be able to use the file/source line number from the dump to
extract the default expression with a relatively simple parser.
