Hello fellow Pharoians (?) from a lonely Swede. I just found out about Pharo (and Smalltalk) two days ago and I'm already loving it :) However, there is a behavior I would like to change, or be enlightened about how it could be done.
As I understand it (bear with me) BlockClosure from Kernel-Methods does not understand (by default?) how to respond to an "anonymous object" (no message name). Is there any way this could be implemented? I'll post an example soon (I currently use both Pharo 7 and 8) If I write the following: [:x | x + 1] value: 3 and evaluate it, I get the expected result, which is 4. That's nice. What I would really like is to be able to just send 3 to BlockClosure and make it repond as above. Like this: [:x | x + 1] 3 or like this: 3 [:x | x + 1] Would this be possible? ----------------------- Also as a bonus, would it be possible to use this for "function composition", "Block composition" or similar? Example of composition: [ :f :g | [ :x | f value: (g value: x) ] ] I could use this construct like this for example: (([ :f :g | [ :x | f value: (g value: x) ] ]) value: [:x | x + 1] value: [:x | x - 1]) value: 5 But… It's a bit wordy. What I would like to be able to do (essentialy remove "value:"): (([ :f :g | [ :x | f (g x) ] ]) [:x | x + 1] [:x | x - 1]) 5. Or in one line: (([ :f :g | [ :x | f (g x) ] ]) [:x | x + 1] [:x | x - 1]) 5. While this might seem obscure, I would really find it useful. Can it be done?
