Hi,
so I'm a newbie getting used to Haskell. I'm writing some
simple things like genetic algorithms in it for practice,
and I keep coming across something that really bugs me:
are there any standard libraries that allow you to
do imperative style for or while loops using monads to keep

Try this:
This line is before the loop
sequence_ $ replicate 10 $ do
line 1
line 2
...
last line
This line is after the loop
Now you can use shorthand via
loopN n block = sequence_ $ replicate n block
So that you can write:
This line is before the loop
loopN 10 $ do
line 1
line 2
