This is in fact the reason for my compose<> template idea: If you can't avoid writing a type expression, you might as well just write that.

BTW, Boost.Egg has the potential to implement your compose. typedef result_of_lazy<fold>::type fold_; typedef result_of_lazy<reverse>::type reverse_; typedef return_of<fold_(reverse_(T_bll_1), T_bll_2, T_bll_3)>::type reverse_fold; A showstopper is that it is difficult to offer static-initialization way.
