for f in F for t in T may be what you want. There’s a spurious comma there.

But realize that will inner-loop t in an outer loop of f:

julia> [(a,b) for a in 1:3 for b in 1:3]
9-element Array{Tuple{Int64,Int64},1}:
 (1, 1)
 (1, 2)
 (1, 3)
 (2, 1)
 (2, 2)
 (2, 3)
 (3, 1)
 (3, 2)
 (3, 3)

You need a space between f and in
