If anyone is interested, I coded a n-args version of unaryFun/binaryFun called naryFun. If you use 'a', 'b', ... as args names, it can automatically determine the templated function arity. So naryFun!"a + b * c - sin(d-a)" is a 4-args template function. It's there: http://svn.dsource.org/projects/dranges/trunk/dranges/docs/functional.html (look for naryFun at the bottom) code is here: http://dsource.org/projects/dranges/browser/trunk/dranges/functional.d It could be simpler now: when I did it 18 months ago, CTFE wasn't so powerful. The looping templates can now easily be done with a simple foreach. This has been on my todo list for quite some time... Philippe
