lazyforward

Simplify maintenance of NSE-SE pairs. Hypothetical dplyr example:

#' @export
#' @keywords internal
mutate_ <- function (.data, ..., .dots) { UseMethod("mutate_") }

#' @export
#' @name mutate
mutate <- lazyforward::lazyforward("mutate_")

The result:

lazyforward::lazyforward("mutate_", asNamespace("dplyr"))
#> function (.data, ...) 
#> {
#>     mutate_(.dots = lazyeval::lazy_dots(...), .data = .data)
#> }
#> <environment: namespace:dplyr>
dplyr::mutate
#> function(.data, ...) {
#>   mutate_(.data, .dots = lazyeval::lazy_dots(...))
#> }
#> <environment: namespace:dplyr>

The difference: You don't need to remember updating the interface and the forwarding logic if the interface of the SE version changes.
