Base.LOAD_PATH — Constant.
An array of paths as strings or custom loader objects for the

import statements to consider when loading code. To create a custom loader type, define the type and then add appropriate methods to the
Base.load_hook function with the following signature:
Base.load_hook(loader::Loader, name::String, found::Any)
loader argument is the current value in
name is the name of the module to load, and
found is the path of any previously found code to provide
name. If no provider has been found earlier in
LOAD_PATH then the value of
found will be
nothing. Custom loader functionality is experimental and may break or change in Julia 1.0.
Base.JULIA_HOME — Constant.

Core.ANY — Constant.
