Smalltalk Keyword names for Javascript method calls

Currently in a message send, keywords after the first are ignored. So:

anObject css: 'background' backColor: 'red'
   and
anObject css: 'background' frontColor: 'red'

both map to
anObject.css('background', 'red')

That can make the ST source confusing. Is there any way possible that Amber can improve this, or is it impossible given the combination of

(a) css:backColor: and css:frontColor: are both valid Smalltalk messages,
(b) everything is dynamic e.g. no way to know the Javascript parameter name used for 'red'.

Thanks!

Btw, I think this cannot be done, but just asking since others here
are waaay smarter than I am anyway :-)

At first it was:
anObject css: #('background' 'red')

But you quickly end up using arrays as parameters everywhere.
So I think the current solution is way better.

And BTW, GNU Smalltalk does the same for the Java binding.
