I hate to say this but...  SRFI-88 and SRFI-89 were submitted along  
with 2 other SRFIs which are good cases for the use of named optional  
parameters:

  - Extensible hash table constructor
  - Extended ports

Could you please wait for these SRFIs to appear and repeat the  
question if you still find that the examples given are not compelling.
