Rejected! Proposals like yours and Laurence's are steps towards the wrong 


Because they add complexity without neccessity. Programs will be harder to 
understand, protocols will be harder to specify and programs will be harder to 
write and prove correct if one always has to keep in mind which type of indexing 
is used today. It looks far clearer to me to have one kind of indexing instead 
of two, even if the one turns out to lead to clumpsy programs at times. Just 
learn to cope with it. At least for the time being.

I'd refrain from trying to mix Smalltalk and C. This leads to monster languages 
like Java, C++ or C#, that are much harder to master than Smalltalk even though 
they start indexing at zero.

The Romans sayed:
	Simplex Veri Sigillum
which means:
	Simplicity is the hallmark of truth
And I'd like to add
	Simplicity is the hallmark of Smalltalk

Greetings Wolfgang
Weniger, aber besser.
