I'm really replying to [2]. There, you wrote:

Well, yes, I would. In fact, I did. Twice. There's org.conman.env [1],
which is a module that just creates a table of all the environment
variables, no functions whatsoever. Then there's org.conman.errno [2] which
is nothing more than a table of system defined errors (like EDOMAIN, ERANGE
etc.).
