I don't think there's any way to cleverly match this. For all we know, 3d could be a version, we have 2019c, 2021a, 1a, 9d, 9100h and 063a already. Perhaps we should forward name and version as keyword arguments, so that we don't have to reconstruct them, or alternatively use a different delimiter (e.g. @)
I'm honestly surprised, that many other stuff "works fine" despite the fact, that they'd probably also suffer from this bug. Can anyone tell me why emacs-2048-game builds?
