The rlang package is currently maturing. Unless otherwise stated, this applies to all its exported functions. Maturing functions are susceptible to API changes. Only use these in packages if you're prepared to make changes as the package evolves. See sections below for a list of functions marked as stable.
The documentation pages of retired functions contain life cycle sections that explain the reasons for their retirements.
These functions are not yet part of the rlang API. Expect breaking changes.
