T.141: if you need a simple function object that is only used in one place, use an unnamed lambda expression

Reason (reason)

That makes the code concise and gives better locality than alternatives.

This approach makes the code more concise and more local than other ways.

Example (sample)

Naming an lambda expression helps improve clarity, even if the expression is used only once.

Enforcement (implementation recommendations)

Look for identical and near identical lambdas (to be replaced with named functions or named lambdas).

Retrieve identical and nearly identical lambda expressions (to replace with named functions or named lamabda expressions)
