Suspicious 'asDynamic' member invocation

Reports usages of asDynamic function on a receiver of dynamic type.

asDynamic function has no effect for expressions of dynamic type.

asDynamic function on a receiver of dynamic type can lead to runtime problems because asDynamic will be executed in JavaScript environment, and such function may not be present at runtime. The intended way is to use this function on usual Kotlin type.

Remove "asDynamic" invocation quick-fix can be used to amend the code automatically.

Example:

fun wrongUsage(d: Dynamic) { d.asDynamic().foo() // <== redundant, quick-fix simplifies the call expression to "d.foo()" }
