I've a minor feature request.

When working on new package definitions, it's often useful to debug
build failures with guix environment.

The current implementation, as I understand it, requires manually
downloading the source, and merely drops you into whatever working
directory you happen to be it.

It would be great if there were an option you could pass that downloads
and unpacks the source somewhere and drops you into the newly unpacked
source directory.

Not sure what to call it exactly, but something like:

  guix environment --with-source hello

Should drop you into an unpacked source directory with the inputs and
such for building "hello".

live well,
