[IronPython] Can I pre-add namespaces?

That seems like a good solution, the perf should be fine.

Maybe it would it be easier just to append it to the text prior to execution.  It didn't appear to have a side effect.  Any performance considerations?

ScriptSource scriptSource = engine.CreateScriptSourceFromString(
"import System\r\n" + script, SourceCodeKind.Statements);
scriptSource.Execute(scope);

I think if you're not replacing Globals on the script runtime you can fetch the namespace from the ScriptRuntime.Globals scope.

If that doesn't work for some reason you can always new up a TopNamespaceTracker, load assemblies into it, and get the namespace trackers from it.  You'll need to get the the ScriptDomainManager object which you can fetch w/ the HostingHelpers.GetDomainManager function.

I know I can load assemblies into the script runtime, but how can I add the imports into the scope programmatically?  I'm trying to avoid forcing people to write things like "imports System" for scripts.

Microsoft.Scripting.Actions.NamespaceTracker seems to be involved, but it isn't there till after the scope executes for the first time and it has no public contructor.

Thanks,
