Sounds great !

But I think the intuitive Syntax in SQL would use ():

CREATE FUNCTION mytype3 ( mytype2 )      RETURNS mytype3      AS 'mytypes.so(mytype2_to_mytype3)'      LANGUAGE 'C'

Syntax:AS <link_file>[(symbol_name)]

This is also how Illustra and now Informix does it.
(Instead of AS they say EXTERNAL NAME)
