As David Nadlinger pointed out, this can already be solved with Instantiate and
ApplyRight. I added a PR to make Instantiate public, and add the solution to
this issue as a documented unit test.

There is, it's just private:

std.typetuple was moved to std.meta, so the request is still valid.

We have ApplyLeft and ApplyRight, which take a template as the first parameter,
and combined with staticMap, could work as long as the parameters are reversed
(the template comes last). Having something that applies a single parameter (or
even multipe ones) to a list of templates would be useful as well, and is
difficult to do directly.

However, I don't think we need a specific function, a helper like this would
work:

template ApplyWith(Args...)
{
   alias ApplyWith = ApplyLeft!(Args[$-1], Args[0 .. $-1]);
}

alias T = staticMap!(ApplyLeft!(ApplyWith, string), leftJustify, center,
rightJustify);

void main()
{
   foreach(f; T)
  writeln(f("hello", 20));
}

It's not perfect. The resulting T isn't a tuple of instantiated templates, it's
a tuple of ApplyLeft aliases, awaiting instantiation.

But a helper like the above would be useful. Is there an "Instantiate" template
that could be used in place of ApplyLeft inside the ApplyWith template? That
might be more proper.

std.typetuple doesn't exist anymore and the idea had never been expressed in a
pull request.
