Note that putting all these features directly in the syntax is not
necessary; see for example how Smalltalk, with its extremely simple
syntax (5 keywords, just a few rules) has the best collection support
I've come across. Much of this is due to the ubiquitous use of Blocks
(anonymous functions) as parameters in the collection library.


"internal iteration"
aCollection do: [:each | each printOn: stream].


"mapping"
aCollection collect: [:each | each squared].


"selection"
aCollection select: [:each | each > 7].
