so the idea is that each parameter declared under  global parameters  would be available via get param  right  i like this on the one hand  because it saves a lot of typing  on the other hand  it brakes self consistency of the single templates  so far  they were valid in themselves and could be used standalone  with the proposed change  get param calls would fail  or are you saying in of proposed changes that the parameter definition would still be there in the nested templates  only the property definition in the containing template could be left out  another idea  what about a get env function that would explicitly get information from the environment just a stupid idea
