..Back to C++, kinda, yeah .. though for the inner_product (and this is where variadic template parameters would be a nice fit):
fusion::inner_product<SequenceA, SequenceB, ...> { /*...*/ }
(, or whatever the syntax was - forgot the exact semantics Doug Gregor implemented)
fusion::inner_product< SequenceA, SequenceB, FunctionSequenceA,FunctionSequenceB
{ /*...*/ }
?
No (, at least I don't see how) ... you'd expect the valid functions to be the operations sensible on sequences A&B both. With this in mind (sequences not variadics), it would be more reasonable to propose the following methinks:
fusion::inner_product<SequenceA, SequenceB, FunctionSequence> { /*,,,*/ }
It occurs that I took the accumulate algorithm and particularised it for dot product. Now you are taking dot product and generalising it back into accumulate :-) , but I could be wrong ... regards Andy Little
