I also hope that my work will be in trunk in the future. But instead of 
big merge of separate brunch I would prefer to produce series of small 
patches. I prepare first such patch. It will allow to parse anonymous 
functions but will not allow to capture variables. Next patch will be 
capturing of variables(it already works). Further refactoring, bugfixes, 
optimizations.
First patch can produce some negative side effect. Next will be safer. 
It should not affect programs which don't use closures.
I uploaded patches for review into mantis. Changes are synchronized with 
latest revision and coding style is fixed.
Fate of this changes is important for me, because it's my graduate work. 
That is why I need feedback from developers. Most important question: 
does my work make sense for you? If someone will find time to attentive 
review then comments about changes quality are welcome. And if first 
patch is ok but have some minor problems then I'm ready to quickly fix it.

Thanks,
Vasiliy
