Hi all,

are the Filter and Expression implementations meant to properly implement 
equals and hashcode?
If so, we are in trouble, as (almost?)none of the FunctionExpression 
implementations does.

For the ones that do, should we move to comparisons based on the geoapi 
interfaces rather than on concrete implementation? I know the geoapi 
interfaces don't impose interface based comparisons. Should they?
I know this way is harder to achieve symmetry, so I'd like to know if there 
already is an agreed position on the topic, or there is place to go the java 
Collections way

just curious.

Gabriel
