should permit iterating a List without declaring a binding

[michaelficarra]

I want to be able to iterate a List using the For each element _e_ of _list_, do notation without having to declare an unused binding (essentially, repeat this a number of times equal to the number of elements in the list). I would write this as For each element of _list_, do, but ecmarkup currently thinks that declares _list_ instead of referencing it.

Why not a loop from 0 to list.length?

[michaelficarra]

It's not as direct.

I also prefer a loop from 0 to the length of the list, and so am not going to implement this.

We talked about this in editor call and are going to explore using Repeat _n_ times: as an alternative.

I get this error when using the suggested form:

Error: spec.emu:47:14: expected "Repeat" to start with "Repeat, while " or "Repeat, until "
Error: spec.emu:47:39: expected "Repeat" to end with ","
