perhaps we're misunderstanding each other? if i define a monadic
assignment operator lifted over monadic lhs/rhs, i can already have
side-effecting lhs/rhs, including post-increments and content lookup.
that's what that example demonstrated, translating everything you
asked for. one can do the same with other operations, such as 
lifting numeric operations over monadic operands (though the 
current class hierarchy may require some ugly dummy class 
instances for that; also, non-overloaded Bool always requires 
some workaround). what is it that you think is missing?
