Same as for the dictionary example below, it is requieres human

Instead of
E1 >> attr
^ attr
E1 >> attr: anObject
^ attr := anObject
you as base programmer will write
E1 >> attr
^self wideVarAt: #attr ifAbsentr: [ nil ]
E1 >> attr: anObject
self wideVarAt: #attr put: anObject
Can't you just collect all such getters and seters and replace them by
the widevar version at compilation time or something (or run some
optimization over a set of compiled classes), as such that the "base
programmers" don't have to worry about it? Should be quite easy to
just detect getters and setters?
