I still have to read your other comments, but the issue of 
wasting memory has already been addressed by suggesting that the 
compiler detect that absence of any actual data in the struct and 
prohibit taking its address or referring to "this" except perhaps 
in the case of "alias someFunction this" to allow it to call that 
function transparently. It would not give the function a pointer 
or anything, the goal being to truly harness the power of 
struct's semantics without paying a price in performance of any 
kind.
