Hi Yuriy,
I though the same. There is a similar situation with pluggable collections
where you have to specify two blocks: one for the hash the other for equality.
So you have to repeat three times the property you're interested in:
PluggableSet new
hashBlock: [ :each | each name hash ];
equalBlock: [ :a :b | a name = b name ];
yourself.
Where I would like to be able to write:
PluggableSet by: #name.
