(Disclaimer: Just to get a throught out of my head.)

Proposal

Having #asSimpleSetter and #asSimpleGetter, add a convenient way to read/write objects having only key/value-pairs at hand. When processing some JSON data, for example. This API reads less "meta" than, for example, #perform: or #instVarAt: ...

Further reading:

Morph >> #setProperty:toValue:
Morph >> #valueOfProperty:
UserInterfaceTheme >> #set:to:
UserInterfaceTheme >> #get:
Dictionary >> #at:put:
Dictionary >> #at:
Object >> #instVarAt:put:
Object >> #instVarAt:
Object >> #instVarNamed:put:
Object >> #instVarNamed:
