Hi,
I am zipping fusion sequences in a series of incremental zip operations:
zip(zip(zip(a,b),c),...)
as a result I am getting sequence with elements like:
vector2<vector2<vector2<a[i],b[i]>,c[i]>,...>
what I want instead is that elements would look like:
vector<a[i],b[i],c[i],...>
What the simplest way to achieve this?
