Sure. But honestly, forcing humans to write non-obvious code is almost
always the exact wrong answer.
When the basic pattern is an obvious and legible one:
if (a < X || a > Y)
saying " use a different helper pattern for this" is the WRONG
SOLUTION. You're making the source code worse.
Make the tools better. Don't make humans jump through hoops because
the tools are spouting garbage.
