3355cadf3f support []byte (more efficient) as well as string in the interfaces.

which used to use 'rm -rf' to remove the _obj directory.

458e23e151 Implement type compatibility and fix places where I thought 
types were supposed to be identical but only needed to be
compatible.  This gets rid of the Type.literal method.  I
renamed the Type.rep method to Type.lit because I believe it
corresponds to the term "literal" as used in the spec.
