Descrizione

Describe the bug

When documenting a type parameter in Kdoc, the only correct way to do it is using the @param tag, for example:

/**
 * @param T the target type to return
 */
fun <T> genericFunc(): T

Unfortunately Diktat reports:

[KDOC_WITHOUT_PARAM_TAG] all methods which take arguments should have @param tags in KDoc: T param isn't present in argument list

Which I believe is a wrong behavior, given that it's taking into consideration the formal parameters only.

Expected behavior

Diktat should not report a violation for the above example.

Observed behavior

Diktat reports a KDOC_WITHOUT_PARAM_TAG
