-------------------------------------------------------------------
Negative values can be used for "skip X and take the remainder". This can't be
done using {{tail()}}, since you would have to know the number of elements
upfront.

> We do support negative values in {{RangeStep}}, e.g. to have an open end
> ({{skip()}} semantics). This is broken in DSEG, probably because we don't
> cover this case in our test suite (not verified).
