Now, who is creative enough to add �dynamic array� (one with curly braces) and temporaries in a block to the original thing:

exampleWithNumber: x
    | y |
    true & false not & (nil isNil) ifFalse: [self halt].
    y := self size + super size.
    #($a #a "a" 1 1.0)
        do: [ :each |
            Transcript show: (each class name);
                       show: ' '].
    ^x < y

Googling around finds various copies of this, but no original source.

I think that it would be interesting to put the syntax on a postcard. It can work as a proof of concept, some addition cheat-sheet for newcomers and also as some king of souvenir.

Hi guys,

we all are talking about the syntax fitting in a postcard, but was there any real postcard with Pharo syntax prototype? This would be really interesting.
