Hi Ludo and Liliana,

Indeed, but the new proposal goes much further with supporting
interactive convenience, in particular via the controversial reading of
guix.scm and/or manifest.scm. That's a convenience I'd like to have
interactively, but not something I expect from an infrastructure tool
that ends up being used in lengthy shell script. For the latter, the
"Zen of Python wisdom" of "explicit is better than implicit" matters a
lot. On the command line, it makes life harder, in particular for bad
typists such as myself.

>   --manifest=manifest.scm

That's a nice idea, but again something I wouldn't want an
infrastructure tool to do. When I use "guix environment" or "guix shell"
in a script or workflow, I want whatever it does to be as independent as
possible from my machine or account, except when I explicitly say the
contrary.

Cheers,
  Konrad
