# ------------
# NOTE: All functions that return lists should use newlines.
# bash functions can't return arrays, and spaces are tricky, so newline
# separators are the preferred pattern.
# To transform a string of newline-separated items to an array, use kube::util::read-array:
# kube::util::read-array FOO < <(kube::golang::dups a b c a)
#

When declaring aliases, it's worth noting that any of the `-`, `_` and `.` characters can be used as separators, but the generated catalog will have all normalized to `.`:
for example `foo-bar` as an alias is converted to `foo.bar` automatically.
