Totally agreed, using dynamic languages, all became a guessing game, everyone is guessing, the IDE is guessing, the programmer is guessing what's inside this variable?

Strange. I'm just asking the Lisp system:

    CL-USER 1 > (class-of *standard-output*)
    #<STANDARD-CLASS EDITOR::RUBBER-STREAM 40E035A2E3>

Oh, the class of the value of

    *standard-output*

is EDITOR:RUBBER-STREAM... From there I can find the source, find the applicable methods, the slots, the super classes...

With declared types programmer is still guessing the meaning and IDE doesn't care anymore.

I think that's the reason dynamic languages work because guessing types is easy for people. Guessing meaning is the hard part.
