> @johnny2002 I guess `ds_$->{0..1}` can work as well. Have you ever tried
it?
@tristaZero YES, ds_$->{0..1} does work.
While I think we shall NOT support ds_${0..1}, I found in our source code,
in order to support "ds_${0..1}", we have to change
StandardEnvironment.ignoreUnresolvableNestedPlaceholders to true. This is not a
good practice, since it will affect the whole application.
