Specifying the Puppet + Ruby Version Matrix in CircleCI

Question

I play with CircleCI as an alternative to Travis using the doll module I wrote. My .travis.yml has a matrix version of Puppet and Ruby and looks like this:

---
language: ruby
bundler_args: --without development
before_install: rm Gemfile.lock || true
rvm:
  - 1.8.7
  - 1.9.3
  - 2.0.0
  - 2.1.0
script: bundle exec rake test
env:
  - PUPPET_VERSION="~> 3.2.0"
  - PUPPET_VERSION="~> 3.3.0"
  - PUPPET_VERSION="~> 3.4.0"
  - PUPPET_VERSION="~> 3.5.0"
  - PUPPET_VERSION="~> 3.6.0"
  - PUPPET_VERSION="~> 3.6.0"
matrix:
  exclude:
  - rvm: 1.9.3
    env: PUPPET_VERSION="~> 2.7.0"
  - rvm: 2.0.0
    env: PUPPET_VERSION="~> 2.7.0"
  - rvm: 2.1.0
    env: PUPPET_VERSION="~> 2.7.0"
  - rvm: 2.1.0
    env: PUPPET_VERSION="~> 3.2.0"
  - rvm: 2.1.0
    env: PUPPET_VERSION="~> 3.3.0"
  - rvm: 2.1.0
    env: PUPPET_VERSION="~> 3.4.0"

I am bothering CircleCI docs, but I see no way to do such matrix testing. Can anyone advise?

From looking at this tweet and in response to "Now, if they would only support support against the ruby ​​matrix, I would use it for OSS too":

@dkubb @avdi stay tuned guys! we're working on it!

It seems that since then there have been no updates ...
