Hi. Today I was giving a lesson and I was trying something something like this:
ByteString allInstances select: [ :aString | aString size > 1000 ] But sometimes, we want (not in this example) delegate the behavior to the object, for example: ByteString allInstances select: [ :aString | aString isTooBig ] And then....I (actually, a classmate told me) realised that Symbol understands value: too. So I can do this: ByteString allInstances select: #isTooBig and it also works :) Interesting, isn't it ? cheers Mariano ps: if everybody already know this, please forgive my completly ignorance
