support runInDebug(() => /* only run in debug mode*/)?

Maybe this already exists, but didn't see the functionality while skimming the source:

usage:

• https://github.com/emberjs/ember.js/blob/ee8ab348484421f254fe995c6f04f0d4a0859cfa/packages/ember-debug/lib/index.js#L134-L157
• https://github.com/emberjs/data/blob/master/addon/-private/debug.js#L19-L21

Ya, the general concept exists but it's more generally used with an if (DEBUG) { /* do stuff */ } instead.
