Map { it } must return an error

[VovaStelmashchuk]

        val data = listOf(0, 1, 2)

        val output = data.map { it }

Expected Behavior of the rule

Detekt return an error. For example map operator don't map

Are Detekt has rule for the case?

[BraisGabin]

Detekt doesn't have a rule to flag that but I think that it would be a nice addition. I saw this issue in my projects too. Do you have the resources to implement it and generate a PR?

[VovaStelmashchuk]

Yep
We will do this in next week

@BraisGabin Do you have any suggest about name of the rule and category (style, complexity, e.g.) ?

[BraisGabin]

I suppose that erroprone is the best fit. Or complexity... I mean, a map that does nothing only increase the complexity.

About the name what do you think about RedundantMap?
