/**
 * Ensures this element is AST-based. This is an expensive operation that might take significant time and allocate lots of objects,
 * so it should be to be avoided if possible.
 *
 * @return an AST node corresponding to this element. If the element is currently operating via stubs,
 * this causes AST to be loaded for the whole file and all stub-based PSI elements in this file (including the current one)
 * to be switched from stub to AST. So, after this call {@link #getStub()} will return null.
