- more debug output if selected
- document diag(), allow suppression of it
- continuation lines in steps?
- excetions from step should be reported neater
- named captures in step def regex
- document context information being carried between steps
- reporting when no features are found should be neater (so should prove6)
- we should have a comprehensive, standalone example in a subdir
- zef integration via plugin?
- what does prove6 do around the 'lib'? does it auto-add it? if so then we should too. if not, does that mean prove6 could test the installed rather than the code from this repo if that line is missing?
