So, is it correct to assume that for language constructs that create built-in types like Range, Array, Hash etc that user-defined initialize methods are never called?

Thanks,

Here, the Proc object is created the normal way.

Here, no Proc is created (blocks are not reified as Proc objects unless
necessary, i.e. by an &-argument).

Here, the Proc object is being created "intrinsically", similar to how Array
objects are created with [], bypassing the generic creation/initialization
machinery.
