I have been away from smalltalk coding for a while. On returning to
the fold, I often see the use of a right arrow in code. Is this
something new?
Today in a Teapot app example, I saw,
Teapot on GET: '/welcome' -> 'Hello World!'; start.
What is the arrow for?
As Sebastian said, #-> is a message that creates an Association, with
the receiver as the key and the argument as the value of the
Association. This has actually been around a very long time, though
perhaps it's getting more widely used these days. It doesn't appear to
be in the Blue Book, but I think it was probably actually in the
Smalltalk-80 image 1 release.
I'm not *quite* curious enough to verify that by rooting around in my
basement for the machine that actually runs that version and seeing if
it will still power up after all these years. :-)
