Batteries[1] includes such an operator in its Std module and its extension of Pervasives. The compose operator is is '-|', and the reverse compose operator is '|-' ((f |- g) x = g (f x)). It also provides the pipeline operator '|>' and its converse application operator '**>'. - Michael 1. http://batteries.forge.ocamlcore.org _______________________________________________ Caml-list mailing list.
