{rlang} as a dependency?

[mmuurr]

Currently {murlib.core} has no dependencies (apart from {base} and {stats}, both part of R's stdlib 'core' subset.
There are some nice tools provided by {rlang} that simplify life and can improve some of {murlib.core}'s utilities, e.g. easier handling of trailing commas in functions taking ... args.

{rlang} itself has no dependencies (again apart from R's core libs), and this is likely to be the case in the future, but isn't guaranteed.

Should {murlib.core} use {rlang}?
