```julia
using Flux
using Statistics

using Networks

export PolicyNetwork, advantage

...

```

I have this source file in the `src` directory of my project. `src` is in the `JULIA_LOAD_PATH`, but when I attempt to `use Networks` Julia pre-compiles for several minutes and uses up all 16 gigs of my RAM?

The file “uses” itself. A recursive import / use. That was the problem.
