If you know that the value is always Just by construction, why don't you express this with the types, i.e. by turning from 'Maybe a' to 'a'? When asking this question myself I could remove fromJusts in most cases. The problem is most oftenly that you drop the information that a value is Just too early and then you cannot recover it later.
Because the function that returns a Just value is from another library or function which for safety's sake should return a Just, but in this case I know that it won't? -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com http://IvanMiljenovic.wordpress.com
