Just for fun - the tiny attached change-set allows #asPipe to get
piping behavior for cascades:

Squeak asPipe
        ps: 'aux';
        grep: 'fabio';
        sort

It makes these two expressions equivalent

        ((((4 + 2) * 3) + 3) * 2)

        4 asPipe + 2; * 3; + 3; * 2

Now I wouldn't use this in production but for interactive exploration
it might actually be useful. Similar to implementing Symbol>>#value:
to allow "(1 to: 10) collect: #squared".

Btw, did you know each class can declare its own parser and compiler
class? Experimenting with the syntax does not necessarily have to
break other's stuff.
