Yes

You need to install the package "NewCompiler", the latest is on  
SqueakSource. Then open the preference browser and enable  
"compileUseNewCompiler" and
"compileBlocksAsClosures".

Please note that I have not yet used the NewCompiler in the latest  
3.9 (with Traits), so it might not work right now...

Now with the Traits integration done, I will integrate into 3.9 all  
overwrites / extensions needed for runtime that are right now in the  
NewCompiler package. This
will be done next week.
