The problem is that everyone has their own definition of "Strong Typing".  
Some take it to mean that you can, by mere examination of the source code, 
make sure that you never perform an inappropriate operation upon an object. 
Others take it to mean that any inappropriate operation will be detected and 
appropriately reported (e.g. via an exception).

Ruby is strongly typed according to the latter definition.  

Few languages are strongly typed according to the first definition.  Java is 
close, Eiffel is even closer, but both rely on runtime type checking to some 
degree.
