List all methods

[Hadley Wickham]

Something like:

library(tidyverse)

methods("format") %>% 
  attr(., "info") %>% 
  as_tibble() %>% 
  rownames_to_column("method") %>% 
  mutate(class = stringr::str_split_fixed(method, "\\.", 2)[, 2]) %>% 
  select(generic, class, visible, from)

May want to consider implementing methods() from scratch — will help understand precise semantics of method lookup.
