^ Please don't nest the eval like this, particularly in combination with
the `raise_api_error if $@` part below.
Better do the `eval { get_groups }` call separately first, check it,
then proceed to the rpcenv-checks. (This also gets rid of the
`@{call()}` construct ;-) )

Please swap ^ and v. Note that `$config->digest()` even crosses over
into rust...
