No, adding bash functions automatically to a Guix environment seems
impossible. The guile function load-profile allows packages to add
path-like environment variables through the search-path-specification
declaration, but not any other environment variables, let alone shell
functions.

That seems reasonable enough. One reason I'd like to move away from conda
is that I don't think the way conda handles environment variables is
tenable. So maybe it is worthwhile to make sure that "conda init" does what
it is expected to do (that is, add the code that loads these bash functions
to .bashrc), even though it is not really guix-y.
