myFunc :: a  -> [b]
(a and b are my own types)

Actually, inside myFunc I used unsafePerformIO (didn't want to change
the whole programm just because of one function). The purpose of myFunc
is to append some value to "some list" lying somewhere (somewhere is
"defined" by IORef), store the resulting list and return a copy. 

I want to do something like this (in a sequence):
append two values to "some list" , then call a function (myFunc2) that 
uses "some list" and return the value returned by myFunc2.
