[Haskell] Silly question on interactive import

Could you remind me what is the easiest way to load interactively a specific module before loading a afile into ghci? For example, I have a file parse.hs with some functions such as isUpper, which belongs to the module Char. I thought that writing :m + Char :l parse would work, but loading destroys the access to the module Char. (:add as well). Well, I won't die if there is no way to do it. But am I obliged to import Char within parse? Of course, interactive import is illegal... Thanks. Jerzy Karczmarczuk
