[erlang-questions] Erlang and bbcode

[Richard O'Keefe]

I wonder if other people are getting the same take-home lesson from bbcode
that I am?  It's

 - we've had adequate notations for describing syntax since
   1960, so why, more than 50 years later, are we using notations
   presented in an informal and incomplete way?

 - we've known about the importance of testing for nearly as long,
   so why, in the 21st century, are things like Markdown and BBcode
   promulgated without a common set of test cases?
