Yes or no, depending on what Sunil wants exactly.
It is impossible  to add a function (or variable) definition
at the interactive prompt, since this would violate the
functionality. But you can type metacommands (beginning with
a colon) to (re)load the source file, and evaluate expressions
interactively (which might cause the animations to move).

The first line (non-IO-part deleted) may be true, but the second
line is IMHO not the reason.
Haskell is rather young, and the population hacking it is not the
one who needs Tkinter, PIL and NumPy everyday.
OTOH, the IO system is well adapted to scan and parse hairy stuff
(there are XML libraries and Haskell compilers in Haskell).

In the interpreter, you can switch on an option which shows
you the type of every evaluated expression together with the
value. The program itself has (AFAIK) no access to this
information. It is neither needed nor available (AFAIK) at
runtime in compiled programs.
 Strictly spoken, this is untrue: One might "load the source file"
