check_dots_unnamed(

)
}
\arguments{
\item{env}{Environment in which to look for \code{...}.}

\item{error}{An optional error handler passed to \code{\link[=try_fetch]{try_fetch()}}. Use
this e.g. to demote an error into a warning.}

\item{call}{The execution environment of a currently
running function, e.g. \code{caller_env()}. The function will be
mentioned in error messages as the source of the error. See the

\description{
In functions like \code{paste()}, named arguments in \code{...} are often a
sign of misspelled argument names. Call \code{check_dots_unnamed()} to
fail with an error when named arguments are detected.
