I just added this to Version:
def assert_spermy expect, version
assert_equal expect,
Gem::Version.new(version).spermy_recommendation
end
def test_spermy_recommendation
assert_spermy "~> 1.0", "1"
assert_spermy "~> 1.0", "1.0"
assert_spermy "~> 1.2", "1.2"
assert_spermy "~> 1.2", "1.2.0"
assert_spermy "~> 1.2", "1.2.3"
assert_spermy "~> 1.2", "1.2.3.a.4"
end
The idea being that tools like hoe and rubygems can use it to help
recommend better dependency specifiers. Right now in hoe if you don't
have a version specifier on a dependency it tells you that you should
at least add "> 0" and this would offer a vast improvement. Eventually
I'd like to push rubygems into if not deprecating then at least
warning against using ">=" specifiers (when used alone).

I also added part of that blog post to the doco on version and pointed
to it from the top level rdoc.
