Demonstrates how regex corpus unit tests work.
Corpus tests allow you to unit test your regular expressions using a typical red => green development flow.

Test sections are marked indicating if the following lines should (#+) or should not (#-) match the regex pattern. Blank lines are ignored. 
 
#+ The following lines will be tested. If they match, they'll be hilighted in green, otherwise they'll be red
mickey mouse.
Mighty Mouse.

#- Nothing below this line should match, if it does it'll show up red
danger mouse

#+ You can switch back to positive matching
Miney mouse

#- And back again. 
Mikes mouse burgers <- Oops, shouldn't match but it does
