I'm not familiar with to_str.  I'll check it out.  I would expect "1" + [2]
==> "1[2]", not "12".

 Well, if you *REALLY* *REALLY* use it constantly then you can write

pigeon% cat b.rb
#!/usr/bin/ruby
class Object
   def to_str
      to_s
   end
end

p ("1" + 2)
p ("1" + [2])
pigeon%

pigeon% b.rb
"12"
"12"
pigeon%

 Be carefull with this ...
