{code:javascript}¯\_(ツ)_/¯{code}
We're getting complaints about how large and un-tree-shakeable the library is
already. I don't see a reason to add more unrelated functionality, especially
when it already exists in other tree-shakeable libraries like Ix.
Otherwise, you can do `for...of` over any iterable type already, or have your
own map implementation (no need to use Ix for something so simple)
{code:javascript}
function* map(source, project) { for (let x of source) yield project(x); }
for (let value of map(vector, (x) => x + 1)) {
console.log(value);
}
{code}
