## digitalmars.D.learn - Given two AliasSeq (A and B) and template T, how to make

• Tofu Ninja (8/8) Nov 26 2016 Basically the title says it all.
• Nicholas Wilson (3/11) Nov 26 2016 AliasSeq s auto expand. so
• Nicholas Wilson (5/13) Nov 26 2016 Whoops it would help if I read your question.
• Tofu Ninja (5/9) Nov 27 2016 That didn't actually work, but I got it working with:

alias A = AliasSeq!(...);

static assert(A.length == B.length);
template T(An, Bn){ ... }
alias C = AliasSeq!(T!(A[0], B[0]) ... T!(A[n], B[n])); // how to
make this :/

How do I actually make the sequence C?

AliasSeq s auto expand. so

alias C = AliasSeq!(A,B);
```

You want to use Iota in conjunction with staticMap.
alias pairs(int N, alias a, alias b) = AliasSeq(a[N],b[N]);
alias C = staticMap!(T,staticMap(pairs,Iota!N));
```
