Easiest way to present Dates

I have been looking for the easiest way to get a date to display with
the desired format.

By adding

BlockContext-write: anObject description: aDescription

^ self value: anObject

The following becomes possible:

^ MADateDescription new
selectorAccessor: #orderDate;
beWithinYears: 2;
stringWriter: [ :i | i mmddyyyy ];
label: 'Order Date';
beReadonly;
beSearchable;
yourself

Is there a better way?
Is this worth adding to the mainstream?

Keith

This is a nice trick. I am not a big fan of unnecessarily adding block-
contexts to my model. As soon as you want to make your meta-model
persistent or editable you run into troubles ...

What I usually did for my applications is to subclass the standard
string writer with my configuration for dates and times to generate
the desired output.

Cheers,
Lukas

Thanks Lukas, I guess I was just being lazy... I conceded in the end.
