I often want to do the following for a large n where I perform some calculations and return a tuple of values with the result of each iteration: function f(n::Int) v = Vector() for i in 1:n ... push!(v, (a=i, b=1.23, c=false, d=:foo, ...)) end v end As written, the code is less ef…

As discussed over in Ridiculous idea: types from the future (as @mohamed82008 mentioned), there is a pretty nice way to do this with map: function f(n) map(1:n) do i (a=i, b=1.23, c=false, d=:foo) end end This is a pretty nice solution, since it’s shorter than the original code while being…
