/**
 * Annotates a method which will be called from "- (void)dealloc" method in the transpiled ObjC
 * code.
 *
 * Annotated method must be private, non-static, have no parameters, return void and there can be
 * at most one such method.
 *
 * This annotation is designed to be used in combination with @Weak (which translates to
 * __unsafe_unretained). It can be used to nullify @Weak references or cleaning internal data
 * structures containing @Weak references, to avoid dangling pointers in transpiled ObjC code.
