This is a nice idea. Expand can probably be replaced by a []. I

foreach (i, element; zip(sequence!"n", MyRange(42))) {

But it's better to not use automatic unpacking of tuples. See
issues 7361 and especially 9817.

Thanks for the tip. std.range.enumerate makes a big difference:
foreach (i, element; MyRange(42).enumerate) {

}

This is a nice idea. Expand can probably be replaced by a []. I
presume this works only if the types inside the tuple are the
same.

That works for me, thanks.
By the way my compiler is DMD 2.066.0

I haven't measured the performance but there is also the following
automatic expansion of tuple members as slice elements:
antropod:
Looks fairly straightforward. But, the second function causes
compilation error:
std.format.FormatException@C:\D\dmd2\windows\bin\..\..\src\phobos\std\format.d(2
585): Expected '%s' format specifier for type 'Tuple!(uint,
uint)'
Can you help me with that?
Currently the "%(%s%)"
