Because all primitive types duck-type to each other by default. An int is a double is a string is an array is an object.

Nope. If you are only using weakly typed languages you will have a very distorted view.

irb(main):001:0> x = 5

=> 5

irb(main):002:0> x.length

NoMethodError: undefined method `length' for 5:Fixnum from (irb):2 from /usr/bin/irb:12:in `'

irb(main):003:0> x = "Foo"

=> "Foo"

irb(main):004:0> x.length

=> 3
