Well, on the one hand, we do want to avoid the need for parentheses:
self color: (self themed: #color)
Hmm... if we are sure that all setters are always named from the getters, then this may do the trick:
Object>>getThemed: aSelector ifNone: defaultValue self perform: (aSelector, ':') asSymbol with: ((self themed: aSelector) ifNil: [defaultValue])
Then
self color: (self userInterfaceTheme color ifNil: [Color yellow])
would become:
self getThemed: #color ifNone: Color yellow
The only hurdle I see is the #asSymbol send which may slow things down a little.
