How to make Squeak use Block Closure

Hi,

I'm wondering how to switch code to block closures. I guess I have to
install NewCompiler from Squeak Source. Right?

Hi,

In the Preference Browser
Go to the compiler category then enable both compileClocksAsClosure and
compileUseNewCompiler.

I seem to remember there's a downside to that. What's the downside again?

- slower perfomance
- problems with the debugger

...and if those are the downsides, what are the upsides? I don't
suppose it means you can save blocks in an OODB or using (Smart)
RefStream, can you?

Well you get full block closures. No more #fixTemps as a starter.

Nah. I thought I heard that Gemstone supports blocks but I might be
wrong on this.

GemStone does support blocks but you need to be careful about what
you reference inside the block. I can't remember all the options off
the top of my head. If the block is "clean", in terms of lack of
global/local references, then you can replicate it to GS. If it is
dirty then I think it fails. The solution normally is to pass the
block across and then send value: to it on the remote side passing in
any objects that you need inside the block. It's pretty neat even
with those restrictions.

Cheers,

Mike

The design is better and so can be easily extended. One can improve the
performance for example :-)
