Maybe we could introduce `@` message, so one can chain them and then even
execute keyword without parenthesis
Dictionary>>@ aKey
^ at: aKey
dict @ 'key1' @ 'key2' @ 'key3'
dict @ 'key1' @ 'key2' @ 'key3' select: [ :each | ... ]
I'm always adding this when hacking around, maybe we could have it in Pharo.
