willey nilley

e.g. I know there was concern about .... naming convention randomly and rapidly changing. I have a lot of code that depends on this naming convention, so it will not change willey nilley.

Without regard for consequences or the will of those affected.
e.g. So people chasing money churn out novels willy-nilly.

Without consideration, an inconsiderate action. e.g. "You can't just invade a country willy nilly"
