&gt; Q: How much of the collections library is covered with full support? Partial support? NYI w&#x2F; ETA?<p>Non-parallel collections should work in first developer preview (to be announced.) Parallel collections may took a few release to get working.<p>&gt;  Q: Cross-platform support? If I wanted to run this on iOS and Android today, what do I have to do? What about on Windows or OSX?<p>If you can compile and run C code with Clang on some platform, it&#x27;s reasonable to expect Scala Native to be run there eventually as we&#x27;re based on the the same underlying compiler toolchain. Currently we mostly aim at POSIX environments.<p>&gt;  Q: How does GC work? Is there a way to take more control over GC for Scala objects?<p>Boehm GC for now, but that&#x27;s not our long-term strategy.<p>&gt; Q: Is it possible to ‘link’ in external dependencies, i.e. Joda Time. How do I do this right now?<p>We can link with libraries via C ABI. Java libraries need to be ported over to Scala.<p>&gt; Q: Does the compiler use a translation layer? If so, is it consistent with Java 7 or 8?<p>We strive to keep the same semantics as Scala&#x2F;JVM.
