It is certainly better.
Now, since #userInterfaceTheme must always be followed by another
selector (else bad things may happen), it seems to me that it should not
be a unary method, but a binary one.
So what about
Object>>themed: aSelector
^ self userInterfaceTheme perform: aSelector
... which of course could be simplified so what we get rid of
#userInterfaceTheme altogether (and actually of the full scoping mechanism):
Object>>themed: aSelector
^ UserInterfaceTheme current get: self class -> aSelector
The usage would be
BalloonMorph new themed: #color
where we now have
BalloonMorph new userInterfaceTheme color
I understand the latest looks better, but I do not think it is worth all
the DNU shenanigans it requires the end user to be aware of...
Best,
Stef
