[julia-users] Re: Tuples of Functions

The problem is not with the return value of the passed functions, it is with inferring the type of `f`. Each function has it's own type and that in turn makes `f` bind to different types (first f1 then f2) in the loop i.e a type instability. On Monday, August 1, 2016 at 5:53:23 AM UTC+2,
