Ayende,
A test is below. It is not the best of tests but should be good enough
to repro. Just run a couple of times. Also got this reply from the boo
group
http://groups.google.com/group/boolang/browse_thread/thread/323a67d7dd84330b
Hope this helps. Thanks again.
namespace TestProject1
{
public abstract class Test {
public int MyProperty { get; set; }
public abstract void Run();
}
public class TestDslEngine : DslEngine
{
protected override void
CustomizeCompiler(Boo.Lang.Compiler.BooCompiler compiler,
Boo.Lang.Compiler.CompilerPipeline pipeline, string[] urls)
{
compiler.Parameters.Ducky = true;
pipeline.Insert(1, new
ImplicitBaseClassCompilerStep(typeof(Test), "Run"));
pipeline.InsertBefore(typeof(ProcessMethodBodiesWithDuckTyping), new
UnderscoreNamingConventionsToPascalCaseCompilerStep());
}
}
[TestClass]
public class UnitTest1
{
DslFactory dslfactory = new DslFactory();
[TestMethod]
public void TestMethod1()

dslfactory.Register<Test>(new TestDslEngine());
var result = Parallel.For(1, 10, p => CreateAll());
}
