How to properly escape ???

[trias702]

I'm creating a ListConfig out of a python list of strings, and one element of my python list is '???', a python string with 3 question marks.

Unfortunately, if I include such a string into ListConfig, and later that ListConfig is part of a resolve call (for example OmegaConf.to_object()), then OmegaConf throws an error for Missing Value, because ??? is a special, reserved phrase.

How can I properly escape ??? so this doesn't happen?

Here's a workaround using resolvers:

>>> OmegaConf.register_new_resolver("three_question_marks", lambda: "???")
>>> cfg = OmegaConf.create("a: ${three_question_marks:}");
>>> OmegaConf.to_object(cfg)
{'a': '???'}

That worked great, thank you kindly!
