I'm not saying that I buy Trans's reasoning for the need for this --
I've long thought that Facets should be a lot more granular than it is
and a lot of the things that Trans has tried to push on Ruby that I
have thought ill-considered over the last two years has been because
Facets is not granular at all.
That said, my understanding of what Trans wants to do is to bundle a
group of gems in a gembundle. That bundle would then silently install
the bundled gems as normal. To put it a bit more concretely, let's use
a simple example:
* I decide to make a Text bundle (version 1.0) that contains
Text::Format (1.1) and Text::Hyphen (1.0) and Text::Reform (0.9).
* I have Text::Hyphen 2.0 installed already.
The Text bundle will install Text::Format 1.1, Text::Hyphen 1.0, and
Text::Reform 0.9 and not touch Text::Hyphen 2.0. Therefore, I will
have Text::Hyphen (1.0, 2.0) in my gem list.
The only problem I can see is the case where I already have
Text::Hyphen 1.0 installed. The concern here is that, for all of the
problems that Mauricio points out with the gem authority issues and
the mirrors, a bundle would represent a more direct way of inserting
malicious code in place of a previously known good version UNLESS the
bundle installer refused to install a version that was currently
I'm still not sold on the concept, but the trick here isn't to add yet
another place for Ruby to look for code, but for a bundled
