Legacy code jabberwocky

’Twas brillig, and the slithy git repos
Did gyre and gimble in the wecks:
All mimsy were the borogoves,
And the mome raths Mutex.

“Beware the legacy code, my son!
The classes that bite, the patches that catch!
Beware the Gemfile.lock, and shun
The frumious monkey patch!”

He took his vim IDE in hand;
Long time the manxome foe he sought—
So rested he by the tab-complete
And stood awhile in thought.

And, as in uffish thought he stood,
The legacy code, with no git blame,
Came whiffling through the tulgey wood,
And crashed frequently as it came!

One, two! One, two! And through and through
The vim IDE went snicker-snack!
He left the bugs dead, and with green tests
He went galumphing back.

“And hast thou slain the Legacy Code?
Come to my arms, my beamish boy!
O frabjous day! Callooh! Callay!”
He chortled in his joy.

’Twas brillig, and the slithy git repos
Did gyre and gimble in the wecks:
All mimsy were the borogoves,
And the mome raths Mutex.
