#' Default value for `NULL`
#'
#' This infix function makes it easy to replace `NULL`s with a default
#' value. It's inspired by the way that Ruby's or operation (`||`)
#' works. Copied from the rlang package.
#'
#' @param x,y If `x` is NULL, will return `y`; otherwise returns `x`.
#' @keywords internal
