 .meth at this point is interpreted as a method call, this is why ruby
 don't expect space before `('

 It's best to see it with 1.7.2 because there is a small modification

pigeon% cat b.rb
#!./ruby -w
class Object
   def meth(arg)
      return arg*2
   end
end

meth (1 or 2)
pigeon% 

pigeon% b.rb
./b.rb:8: warning: meth (...) interpreted as grouped expression
pigeon% 

pigeon% cat b.rb
#!./ruby -w
class Object
   def meth(arg)
      return arg*2
   end
end

meth(1 or 2)
pigeon% 
pigeon% b.rb
./b.rb:8: parse error
meth(1 or 2)
         ^
./b.rb:8: warning: useless use of a literal in void context
pigeon%
