The "@trusted" means that you promise this thing is safe, even if the compiler can't be certain.

If toDelegate isn't (always) @safe, how can you be sure that your wrapper is? Also, TFunc may have an unsafe destructor.

That's not good use of `@trusted`.

Could you elaborate on the unsafe destructor please? Are there any other gotchas ?
