Sur les classes de base, il s'agit généralement d'inspecter.

Par exemple:

irb(main):001:0> puts "array is: #{[1,2,3].inspect}" 
array is: [1, 2, 3] 
=> nil 
irb(main):002:0> puts "array is: #{[1,2,3]}" 
array is: 123 
=> nil 
irb(main):003:0>

FWIW, Inspect est probablement plus comme __repr__() que __str__()

de la référence de la bibliothèque ...

Called by the repr() built-in function and by string conversions (reverse quotes) to compute the ``official'' string representation of an object. If at all possible, this should look like a valid Python expression that could be used to recreate an object with the same value (given an appropriate environment). If this is not possible, a string of the form "<...some useful description...>" should be returned. The return value must be a string object. If a class defines __repr__() but not __str__(), then __repr__() is also used when an ``informal'' string representation of instances of that class is required.
