Question: Using read to set a variable

[ScottFreeCode]

I sometimes use read PASSWORD to put a password into an environment variable without entering it into my shell history. (Sometimes I export PASSWORD afterwards, depending on what I'm passing it to.)

Could envy set namespace VARIABLE with no = be shorthand for envy set namespace VARIABLE="${VARIABLE}"?

Or could there be an envy command equivalent to read VARIABLE?

(Or, is either of these already a thing? I just looked at the documentation in the readme.)
