Wonderful!
~ i thought descriptions started with a hyphen C<->, not an octothorpe C<#>.
Descriptions may start with any character so long as it's not a not a digit or
an octothorpe. Octothorpes are not allowed in descriptions unless escaped.
That was also something else I didn't know how to represent in my grammar:
description ::= (character - (digit '#')) {character - '#'}
Hmm, but that should be:
description ::= (character - (digit | '#')) {character - '#'}
The reason you see descriptions starting with a hyphen in Test::More style
output is because people do stuff like this:
ok $foo, '3rd test passed';
And you don't want to risk that leading digit confusing the parser. Of course,
whitespace between the test number and the description would make that a moot
point, but since test numbers are optional ...
~ doesn't <directive> belong before <description> ??
No. Consider:
not ok 3 we should have foobar # TODO find some foobar
Status: 'not ok'
Test Number: 3
Description: 'we should have some foobar'
Directive: '# TODO find some foobar'
~ missing 'Bail out!'
Phooey! Thanks.
Um, that raises an interesting question: is anything allowed after Bail out?
I see that in some of the sample tests, but I'll try and figure out those after
I get off work.

That sounds great!
