You can just not compile a hard dependency on System.Core, and instead import
it manually. Basically, create a plug-in style architecture for dealing with
it:
Start: DLR
Import: DLR + LINQ-for-DLR plugin (+ System.Core, required by plugin)
So such a plugin would be importable, and then it could register itself as a
service to handle specific points in processing. If no such service is loaded
and registered, processing continues as normal (eg, .NET 2.0-level).

The good news is this is basically inevitable but will take some time to
achieve :). In the latest source code, I guess currently available only
through the IronRuby SVN, you'll see that the namespaces of the DLR expression
trees have moved to System.Linq.Expressions. This is the completion of making
the DLR expression trees into a superset of the LINQ expression trees.
Unfortunately both of your features require taking a dependency on .NET 3.5 (or
some future version) which we're just not quite ready to do. But ultimately
this should be trivial in the future - it's just not going to happen in 1.x and
probably not 2.x. But the lambdas -> expression trees is probably a little
easier as it's just add some new conversion support - C# 3.0 extension methods
have scoping design issues.
Anyway obviously this is something we care about too but it serves as a good
excuse to mention some cool recent code changes :).

(Python lambdas to CLR Expression Trees.. my one wish aside from C#3-style
extension method resolution)
(but y'all knew that, anyway)

Yeah, it's not going to happen today :) The changes are done (any bugs
assigned to me and the 1.1.2 release on CodePlex will be fixed), they just need
to run through a full test pass. I got started on the changes late and the
test infrastructure needed to be brought back to life so it's taking a little
bit longer than expected but the RC should be out soon.
Beta 4 is currently planned for early August. If you're willing to try out a
source release from
http://www.codeplex.com/IronPython/SourceControl/ListDownloadableCommits.aspx
I'd be happy to let you know when the last remaining regression is fixed (and
gets uploaded there - looks like that hasn't been happening :(). We've fixed
the polymorphic call site perf bug already but there's still a bug that results
in massive overhead of calling simple Python functions.

Hello guys,
A while back you suggested that IronPython 1.1.2 would arrive 'some time
in June'. Whilst that is still possible it seems unlikely, any news on
an eta?
Whilst we're at it, any idea on when IP 2 Beta 4 might be released? We'd
like to test Resolver One with an updated IronPython 2 where performance
isn't borked quite so much... :-)
Michael
