Thats real weird that it would reject your "i" variable, given that
T.length is known at compile time. I think this is a bug. I can get your
code to compile if I change your foreach loop to this:
foreach(i, U; T)
modTuple[i] = transTupleElem(argTuple[i]); // ok
That works indeeed.
I also tried "foreach(int i, x; argTuple)" which also with the same
error as "foreach(i ; 0 .. T.length)".
As a workaround I created a TupleIndices template, that would return a
tuple with 0 .. len and did "foreach(i; TupleIndices!(T.length)" but
that was kinda messy and reminded me of the loops I had to jump through
in C++ to do anything useful with variadic templates..
I agree that this is a bug, but at least your workaround is much nicer,
thanks a lot! :-)
Cheers,
