Re: [Boost-users] [Bind] arity of arbitrary object

-----Original Message----- From: Sohail Somani arity( _bi::bind_t ) :- max( arity( e ) ) for each e in L arity( X ) :- is_placeholder<X>::value This could be much easier with a bind that uses a fusion tuple as L. :-) ------------ Ok so now the attached version doesn't have the issues which you pointed out. Is there a way (using mpl) to get the max element in a sequence? ------------ Argh, bind(f,1,2) has incomplete type. Will fix later :) ------------ Ok the incomplete type was because there was no specialization of _bi::value<T> which occurs when the user actually supplies a value. Does this solve the problem then?
