I was trying to...
This has been also described in #1622. My case is a TypeORM entity collection where I also use class-validator decorators. One of the entities is a polymorphic entity, therefore I use discriminator at the type to determine the type. However, since the type has a reverse relation, it results in circular dependency.

The problem:
Normally I avoid type-level circular dependencies by using type X in the import. However, since this is a runtime usage, I cannot avoid the class reference.
