Regex matching calling method

Want to capture the calling method? Plus three different methods of extracting the match.

2.2.6 :009 > c = caller(1..1).first 
=> "/Users/roblacey/repos/something/blah.rb:192:in `pages'" 
# scan(pattern) → array
2.2.6 :014 > c.scan(/`([^']*)'$/).join
=> "pages" 
# match(pattern) → matchdata or nil
2.2.6 :015 > c.match(/`([^']*)'$/).try(:[], 1)
=> "pages" 
# str[regexp, capture] 
2.2.6 :017 > c[/`([^']*)'$/, 1]
=> "pages"
