At the moment it seems that there is no syntactic different between the name and the version number in the output of Guix.
The other day I tried to extract the version number of package
dependencies with "everything after the last '-'", until I stumbled on
the following:
> guix package --show=ncdu | recsel -R dependencies
ncurses-6.0-20170930
Here the version number contains a '-'. Because of this it makes the
problem undecidable I think.
Would it be possible to separate the package name from the version
number with '@' instead?
