* `true` if this package fragment is loaded during compilation from the current compiler's class loader.
* This fallback package fragment is useful because standard types like kotlin.String, kotlin.Unit will be resolved to something
* even in the case of absence of kotlin-stdlib in the module dependencies. So, the code in the compiler that relies on these types
* to be always there, will not crash.
* However, if anything in the source code references anything from the fallback package, this is a compilation error because it means
* that there's no kotlin-stdlib in the dependencies and the build is compiler version-specific, which could lead to weird issues.
