[Seaside] A new critical blog discussing Seaside - Using getters/setters

[Richard Peirson]

I agree entirely with the points being made by both Michael and Frank on
this topic.

In fact, based upon this quote taken from Mr. Cucumber's Proposal #1 in his
Blog, it appears that he does too . . .

7) Accessors for other internals
Of course, the same as stated in 6) is true for all other instances held by
WARequest in its instances. It is never good to let foreigners (classes
outside WARequest) know about implementation details inside another class!
To reming [sic] you: This is what is called encapsulation in the schooldays
for Smalltalk.

This sounds, to me at least, to be suggesting that an accessor should be
implemented only if you want to expose that "implementation detail" for use
by other objects. Am I misinterpreting the statement?
