For example, in this sequence:

```julia
(@v1.8) pkg> activate a
  Activating new project at `~/a`

julia> Base.load_path()
4-element Vector{String}:
 "/home/jishnu/a/Project.toml"
 "/tmp/jl_wT5lem"
 "/home/jishnu/.julia/environments/v1.8/Project.toml"
 "/home/jishnu/packages/julias/julia-1.8/share/julia/stdlib/v1.8"

(a) pkg> activate b
  Activating new project at `~/b`

julia> Base.load_path()
4-element Vector{String}:
 "/home/jishnu/b/Project.toml"
 "/tmp/jl_wT5lem"
 "/home/jishnu/.julia/environments/v1.8/Project.toml"
 "/home/jishnu/packages/julias/julia-1.8/share/julia/stdlib/v1.8"

```

How do I add both `a` and `b` to the load path, other than explicitly modifying `LOAD_PATH`?

This is how you do it.
