|laziness, impatience, and hubris|
This isn't actually very lazy.
Besides having to remember to keep the number of BEGIN blocks synchronised with the addition and removal of tests, if you ever do get out of sequence in anything other than the most trivial of tests files, working out which of the BEGIN blocks needs to be adjusted is a total pain in the neck.
This is especially true if someone else made the change that threw the sequencing out.
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
