I second that: the language should help make code consistent. I don't 
really care which syntax is kept in the language, but in my opinion 
Walter should decide on one, not two.

Allowing both seems like a compromise to make C++ switchers happy by 
permitting const at the end of a member function (as in C++), but I 
think it just makes the differences about const even more subtle and 
thus harder to learn to that group.

Or is there another rationale I'm missing for having the two syntaxes?
