Code review comment for lp:~niemeyer/pyjuju/no-regex-option

hmmm.. i almost think its worth changing the constructor to include the formula name for this case. Giving warnings on potentially third-party formulas isn't particularly useful without identifying the formula in question imo. The primary role i'm concerned about isn't the formula-author but the ensemble user consuming formulas. All that said, at this point those roles are a perfect intersection.
