Nice :)

This Slice adds an API to the compiler to set a dictionary with
bindings to be taken into account.
They are compiled as pushLinteralVariable: (thus refer to the
association of the dictionary)
Smalltalk compiler
bindings: { #a -> 3 } asDictionary;
evaluate: '1+a'.
Internally this for now (ab)-uses the #requestor: API... later we will
change this to be inverted: the requestors
should privide binding and get notified using Announcements.
