# It would be nice to have a fixed array of arguments passed into

# `format()` so all you need to provide is a format string, but

# unfortunately, that does not work easily

# due to https://github.com/hashicorp/terraform/issues/28558

# which requires that the format string consume the last argument passed in.

# We could hack around it by adding then removing a trailing arg, like

#

# trimsuffix(format("${var.format_string}%[${length(local.labels)+1}]v", concat(local.labels, ["x"])...), "x")

#

# but that is kind of a hack, and overlooks the fact that local.labels

# drops empty label elements, so the index of an element is not guaranteed.

#

#

# So we require the user to specify the arguments as well as the format string.

#

# There is a lot of room for enhancement, but since this is a new feature

# with only 2 use cases, we are going to keep it simple for now.
