\ifelse{html}{\href{https://lifecycle.r-lib.org/articles/stages.html#deprecated}{\figure{lifecycle-deprecated.svg}{options: alt='[Deprecated]'}}}{\strong{[Deprecated]}}
\code{with_mock()} and \code{local_mock()} are deprecated in favour of
\code{\link[=with_mocked_bindings]{with_mocked_bindings()}} and \code{\link[=local_mocked_bindings]{local_mocked_bindings()}}.
These functions worked by using some C code to temporarily modify the mocked
function \emph{in place}. This was an abuse of R's internals and it is no longer
permitted.
