#11719 No way to unset an option via CLI and env var Issue created by Eric-Arellano We have several options that are optional, like

str | None

. If the option is set via a config file, the only way to unset it is to modify the config file - there is no CLI or env var override.

--opt=''

sets to the empty string.

--opt=None

sets to the string "None". It's not clear how this should be modeled? Should we special case

None

to be

None

instead of the empty string? How, then, would you get the string value? pantsbuild/pants
