Dataflow requires accounting for the fact that the varargs parameter isn't necessarily last in the parameter list in a couple more places. Default handling just requires that if the only null parameter is the varargs argument, and it has no default value, then no $default method is required-- the caller is expected to simply pass nothing (at QL
/ source level) or an empty array (at JVM level).
* Extract varargs as if they are ordinary positional arguments
* Adapt the QL that distinguishes varargs from ordinary arguments to account for Kotlin's varargs which can occur in the middle of the arg list
* Add a test checking dataflow through varargs which doesn't work yet due to array-get and array-set not being extracted as IndexExprs
* Extract the special case arrayOf(*x) as a clone call, which is (equivalent to) the Java lowering of that operation
