 Can templates notation be extended to use optional named
 parameters (onp). I am thinking in:

 Template definition:

 [template tname [a b c]
     [onp_1 default_1]
     [onp_2 default_2]

 This is the template body...
 use unamed forced parameters: [a]
 use onp parameters: [onp_1] (This prints the value or the default)
 [onp_1? if was used do this : if not do this ]

 ]

 IMO this is a good extension and is backward compatible with the
 current implementation.
