just want you to show the evolution from your original scheme (spot the difference) to that of roberts (retaining your original inlining)

C:\family\ruby>cat -n try.rb
     1  puts "---scheme 1---"
     2  r = ['KLP','OGN']
     3  msg =<<MSG
     4    #{puts "Found #{r.length} orders"}
     5    #{r.map.each_with_index{|v,i|  puts "(#{i+1})  #{v}\n" }}
     6  MSG
     7  msg
     8
     9  puts "---scheme 2---"
    10  r = ['KLP','OGN']
    11  <<MSG
    12    #{puts "Found #{r.length} orders"}
    13    #{r.map.each_with_index{|v,i|  puts "(#{i+1})  #{v}\n" }}
    14  MSG
    15
    16  puts "---scheme 3---"
    17  r = ['KLP','OGN']
    18  puts "Found #{r.length} orders"
    19  r.each_with_index{|v,i|  puts "(#{i+1})  #{v}\n" }
