Default value for field with no value specified / required field

[breengles]

Hi!

Is there any way to specify that some field is required (see, e.g., click's required option)?

Also, by default one cannot use field from dataclasses with no default value (with every other parameter left also by default) while with pyrallis it is replaced with None value instead. Although, personally I am not having any problem with that (even more, with that behaviour, I can somewhat manually check for required fields via assert some_value is not None for example) but it would be much cleaner if such required options are available.

Any update of this?
