yes but that variable is lost when you go into a new .wdl, so if you create var super_global_var = 20; in "supercool.wdl", just because you import "supercool.wdl" in your "justfine.wdl" won't make (when you try to edit) super_global_var = 30; a valid paramter, your code will yell at you saying "what in the world is this super_global_var, tell me if i'm wrong about this, but I think that is how it works, I havn't tried this out in a while.
