Hello!
"Thompson, David" <dthomps...@worcester.edu> skribis:
I have long thought that --ad-hoc should be implied, as that is the

default.
I very much agree with that. I don’t think ‘--pure’ should be the
default, because there are valid use cases for that.
As for ‘--ad-hoc’: making it the default is technically easy. The
difficulty is to come up with a nice transition/deprecation mechanism so
that we don’t break everyone’s script overnight.
Ideas on how to achieve it are welcome!
Thanks,

I suppose the straightforward way of doing such a transition would be:
- In the next release, add --inputs-of and make the use of 'guix
environment' with neither switch emit a warning saying you should use
the new switch to explicitly enable it because the default will change.
- Later, change the default behavior and deprecate --ad-hoc as it
becomes a no-op.
- (Optional) In some future release, remove --ad-hoc.
