I thought there was some suggestion in the past that we should move some 
in that direction. The discussion context was Theo Schlossnagle's 
complaint about the overhead of passing bytea to and from PLPerl, 
although that might be ameliorated by the hex gadget. The other major 
case that would benefit would be passing Array values as the PL's native 
array type, and Composite values as the PL's associative array type. 
That would save PL users a lot of highly error-prone coding 
deconstructing the text representation of such objects.
