[Does] Haskell allow me to define a function at run time? I know Lisp can, since a function is just a data structure which we can put together at run time. But how about Haskell?

If you write a good parser, you can also
do putStrLn "Please enter function code:" code <- getLine let fun = parseFunction code use fun -- may segfault if the entered code isn't good
In which (other) ways can you construct functions at run time in Lisp?
None. I guess the only difference, if so considered, is that since Lisp is so much syntactically simpler, it's easy to write a parser for it, and I guess most implementations already bring one for ya. And that's nice. It allows for the code that write code, which sounds great. But anyway, my interest here was understanding Haskell better, which I now do. Thanks for all inputs in this subthread.
