[Cuis-dev] change image in ImageMorph

[Hernán Wilkinson]

Ha ha ha, you are right!
Statements are used in the programming language parlance and in this case
as a way to simplify the “receiver message” syntax…
It could say “collaborations” but an assignment it is not a collaboration…
Anyway, the thing is that you were not looking for an statement but for a
message … you can say that syntactically the message send (collaboration)
was going  to be express in a statement, but you needed the message

Cheers
Hernan
