Nope. The autocompletion available in the editor is somewhat limited to static 
information contained in the API files or the current document. The eric4 
Assistant plugin extends this to provide autocompletion for the current 
project as well. This is updated as soon as a file belonging to the project 
is safed. Having dynamic autocompletion like in the shell would mean to run 
an interpreter in the background executing the current code, which might lead 
to unwanted effects (like windows popping up).
