'Function to evaluate haskell in ghci while editing source file using Emacs

I'm editing a haskell source file. I want to run my main function in my inferior-haskell buffer (already opened in a different frame) and continue editing my source file. To do this, I do

C-c C-l, change frame, main<ret>, change back to original frame

This seems quite inefficient. I'd like an emacs function/key that does it one shot.

To use interactive-haskell-mode, I found a similar setting than the other answer:

(defun my-haskell-load-and-run ()
  "Loads and runs the current Haskell file main function."
  (interactive)
  (haskell-process-load-file)
  (haskell-interactive-mode-run-expr "main"))
(defun my-haskell-mode-hook ()
  (local-set-key (kbd "C-x C-r") 'my-haskell-load-and-run))
(add-hook 'haskell-mode-hook 'my-haskell-mode-hook)

But I have a small issue with it, it always jumps to the end of the source buffer... which can be annoying.
