someVar!!.someMethodCall()
In that specific case, you can use the predicate `Expr.getUnderlyingExpr()`. This goes directly to the underlying `VarAccess`` to produce a more similar behavior to that in Java.
In that specific case, you can use the predicate ``Expr.getUnderlyingExpr()``. This goes directly to the underlying ``VarAccess`` to produce a more similar behavior to that in Java.
Nullable elements (`?`) can also produce unexpected behavior. To avoid a `NullPointerException`, Kotlin may inline calls like `expr.toString()` to `String.valueOf(expr)` when `expr` is nullable. Make sure that you write CodeQL around the extracted code, and do not directly modify the source code in the codebase.
