Yes. That is whatever output you would see when in interactive mode, if
that makes any sense...

That does not seem to matter in other scripting languages, such as Tcl or
Perl: calling an internal eval C function with a script as argument returns
the result of the script (not what comes out on stdout or stderr), which
may be empty.
For example, if I define a function foo that returns a string, invoking
eval("foo()") in C would return that string. Is not that the behavior of
python in interactive mode, for example?
