For me, yes. I'm slowly working on it, looks quite promising. The  
plan is to
have the new compiler optionally available quite soon.

Then this needs a quite hard testing phase, as it's a real critical  
part of the infrastructure.

This compiler can create both old-style blocks and closures, and it's  
easy to turn
it off completely and just use the old one.

I'm now working on getting all the infrastructure into 3.9 (merge the  
overrrides, add the code
needed for the closures-runtime code...). When that's done, the  
newcompiler will
be a module: drop-in, easy to load and unload, no patch needed.

It should be made clear that the closure runtime would only be used  
when compiling
code with the new compiler in closure-mode, so this change will have  
no impact at
all for performance or stability.

The new compiler is quite nice... nothing is perfect, of course, but  
it's a promising starting point.
One thing that it does quite well is to enable experiments: The  
backend is reusable for other
compilers and makes it very easy to muck around with bytecode (see  
ByteSurgeon), the RBAST
is a good startingpoint for making lots of stuff easier and cleaner,  
and the SmaCC based Parser
is easy to change (if you get to now how to use SmaCC), and so on.
