I do use --with-latest for testing package upgrades. But it is tedious to type

$ guix build X --with-latest=X

in order to test the latest package.

What would be nice is if

$ guix build --latest X

is an equivalent command. Certainly a shell script could take care of that:

guix-build-with-latest() {
    guix build "$1" --with-latest="$1"
}

but having it done in guix itself would be convenient.

It could be an option to guix refresh, for example

$ guix build --latest X --export-patch

would build X with the latest version and export a patch with an appropriate commit message (like marking failed builds with DRAFT). This would help users contribute without having to clone the git repo.
