Yes, in fact, going this route would allow us to write a version of
'function<>' class that would take _less_ space than the current
implementation (1 function pointer + 1 data pointer, instead of current 2
function pointers plus + 1 function/data pointer).

So, returning to the original suggestion ('bind(&my:foo, this)'
optimization) - can we have it? :)
