Hi,
I want to do exactly the same as described in
http://d.puremagic.com/issues/show_bug.cgi?id=4536 . The problem is I
can't even get the workaround to work. Dmd complains about the following
template:
---------------------------------------------------------------
template Init(T...)
{

alias (Tuple!T.init).expand Init;
}

Hmm, I'm pretty sure it used to worked, because as one time that's what I used.

Anyway, Simen's solutions is better, a bit less dependency. TypeTuple is a bit more universal than Tuple.

Simen:

template Init( T ) {
alias TypeTuple!( T.init ) Init;
}

template Init( T, U... ) {
alias TypeTuple!( T.init, Init!U ) Init;
}

And, looking in my codebase, here is what I'm using ;)

template Init(T...)
{
T Init;
}

It's so simple...
I think I found this before the bug report and then forgot about it and copied an old version. I'll update the bug report accordingly, if the latter version works for you.
