Well, there are a few things I could suggest for you to look at:
* the hint package [1] for runtime Haskell interpretation
* look at xmonad [2] for an example of a program which recompiles and reloads itself on the fly
* the haskell-src-exts library [3] for a full-featured Haskell parser/pretty printer
There is no way to actually inspect and modify the structure of a
running Haskell program in memory; it is simply not stored in a format
which would let you do this (it is highly optimized and compiled).
However, using the above tools I imagine you should be able to
accomplish what you want.

Hi. Someone has performed or know how to use reflection in Haskell? I've found something on google, but that stuff seems to me very confusing.
It depends what you mean by "reflection". Can you give an example of the sorts of things you'd like to do? Generally speaking, Haskell doesn't support "reflection" in the same way as many other languages do, but there are usually idiomatic ways to accomplish the same things you would use reflection for.
