Manuel, is this something you might look at in due course?

| Enumeration doesn't work in parallel array comprehensions:
|
| {{{
| nums = [: 0 .. 100 :]
| }}}
|
| causes a compiler panic. Interestingly, the panic seems to happen
| before typechecking because if we add some nonsense:
|
| {{{
| other = 5 / "bad"
| nums = [: 0 .. 100 :]
| }}}
|
| it still panics.
