Yeah, you definitely don’t want to do that–you are creating two completely unrelated modules called `M1` by calling `include()` twice. If you’re familiar with C++, this would be like including the same header outside of _and_ inside of a namespace.

You don’t need to use projects for this (although projects are incredibly useful). Just add the current directory (“.”) to your `LOAD_PATH` and get rid of all your `include()` calls:

```julia
julia> push!(LOAD_PATH, ".")
4-element Array{String,1}:
 "@"
 "@v#.#"
 "@stdlib"
 "."

julia> using M1
[Info: Precompiling M1 [top-level]

```
