[Haskell-beginners] REPL with visualisation

[Ondrej Nekola]

Hi
Just curious: is there some recommended "first choice" combination of 
REPL and libs for (Apple) Swift styled "playgrounds"? (I have just seen 
a fractalish coffee spill and remembered that I have not implemented 
Mandelbrot set since high school and Pascal days and maybe it's time to 
be a bit childish again).
Thanks
