## 0.5.2

### Minor Analysis Improvements

* Fixed data flow through variadic function parameters. The arguments corresponding to a variadic parameter are no longer returned by `CallNode.getArgument(int i)` and `CallNode.getAnArgument()`, and hence aren't `ArgumentNode`s. They now have one result, which is an `ImplicitVarargsSlice` node. For example, a call `f(a, b, c)` to a function `f(T...)` is treated like `f([]T{a, b, c})`. The old behaviour is preserved by `CallNode.getSyntacticArgument(int i)` and `CallNode.getASyntacticArgument()`. `CallExpr.getArgument(int i)` and `CallExpr.getAnArgument()` are unchanged, and will still have three results in the example given.
