Hi,
Would be great if we had in the System module functions similar to those
that we have right now in the Application module.
`System.get_env/2` could accept a default value similar to
`Application.get_env/3`. I always find myself using System.get_env("VAR")
|| "DEFAULT VALUE".
And we could have `System.fetch_env/1` and `System.fetch_env!/1`. The
fetch_env!/1 I would use a lot. Normally you want to raise an error if the
variable does not exists and would be great if the already existed an
function to do that. Right we have to use Map.fetch!
`Map.fetch!(System.get_env(), "VAR")` or create our own custom function
that raises an error. I think that as it is a common use case would make
sense to include this functions in the language.
What do you guys think?
Thanks,
Thiago
