I’ve recently been messing around with anonymous functions and loops, trying to generate arrays of functions that are “nested”, i.e. a function generated in a given loop iteration uses functions from previous loop iterations.

I think an example will best explain it.

```
arr = Array{Function,1}([x -> x + 1])
for i = 1:10
push!(arr, x -> arr[i](x) + 1)
end
```

I start off the array `arr`

with the anonymous function `x -> x + 1`

, and then in each iteration of the loop, push another anonymous function on to the array that takes the previous iteration’s function and adds one to its result: `push!(arr, x -> arr[i](x) + 1)`

.

This works as I’d expect, given that the following loop prints the sequence 2 to 12.

```
for func in arr
println(func(1))
end
```

But when I look at `arr`

in the REPL, I get:

```
julia> arr
11-element Array{Function,1}:
#104 (generic function with 1 method)
#106 (generic function with 1 method)
⋮
#106 (generic function with 1 method)
#106 (generic function with 1 method)
```

It’s always the same pattern – the first element is a certain #-number, and **all** of the other elements are the same other #-number. Why is this? Like I said, I get the functionality I want, but shouldn’t the #-number be different for every function in the resulting array, as they are “different” functions?
