the package (including its non-Go source files) will be recompiled.
Note that changes to files in other directories do not cause the package
to be recompiled, so all non-Go source code for the package should be
stored in the package directory, not in subdirectories.
The default C and C++ compilers may be changed by the CC and CXX

or cast of any kind, because it lacks the information to know that the types are
OK. In such cases, you can use
the [`Types.forciblyCast`](libs/core/src/main/java/org/elasticsearch/core/Types.java)
utility method. As the name suggests, you can coerce any type to any other type,
so please use it as a last resort.
