[PEAK] dispatch -- more specific

[Simon Belak]

Hi,

is "more specific" just a measure of the number of logical expressions 
in a case or is there more to it than that?

What I would like is a strategy where equals (==) is more specific than 
other relations (e.g. isinstacnte).
Any pointers on how to do that or where in the code to look (I know I am 
a bit lazy but it is quite a bit of not very trivial (to me) code to 
wrap my brains around, therefor a stating point would be appreciated).

Thanks,
Simon
