[Rubygems-developers] Gems as Ruby programs (or not)?

[Chad Fowler]

At the Software MFA program I attended in Illinois recently, I was talking 
about RubyGems with one of the other attendees and he started really 
grilling me on why the gem files (not the specs) are Ruby programs.

He did a pretty good job of convincing me.  By the end of the 
conversation, I couldn't really think of a good reason (that would 
outweight the negatives--mainly security issues).

Any thoughts?  Is there some reason that I've forgotten?
