Not sure i follow in my groggy state.  CellRendererCombo inherits from 
CellRendererText, so the text attribute is valid.  It's also perfectly 
valid to use a subroutine for the attr (the manpage has an example).

SimpleList's column types are designed to map one column's value to one 
cellrenderer's property; if you need two for the CellRendererCombo, 
then, yes, you'll have to do something manual.

Note that it should be possible to use the SimpleList's TiedList class 
to tie a model, and use that model with your own view implementation.  
(The real attractive feature is the tied behavior, after all.)
