if we get named parameters, then we should also be able to get a tuple of 
parameter names.

maybe something like this:

is(typeof(fn) args = function);
is(fn argNames = names);

args val;
foreach(name; argNames)  val[name] = typeof(val[name]).init;



this would make my argument biding template(*) more robust.

static int fnc(int that, char has, bool lots, int[] of, float args)

// bind some args
alias Args!  (0,2,4).Become!(1,true,1e7).For!(fnc).Gives fn2;

vs.

alias Args!  (that,lots,args).Become!(1,true,1e7).For!(fnc).Gives fn2;
