World: r3wp

-  No multithreading support

- Mostly glue languge, not general purpose enough

What is the state of the REBOL world

What is the new project announcement?

we are now busy with it

be patient

And where it is today

What to do then?

Give up and pick another language

or build an alternative?

Nenadn chooses the second one

My answer is Red

Red[udeced] REBOL dialect

Fully open sourced (MIT/BSD)

Statically compiled + JIT compiled

Parllel programing support

parllel = parallel

general purpose (system programming support)

cool! Any ETA? (in months, years?) :-)

Can be used for scripting like REBOL (REPL console)

how much is it similar to REBOL syntax-wise?

@ Pekr, Nenad answers that in last slide

ok, so will slides be available later? I can wait. Good news indeed 
:-)

yes

Easily embeddable in other apps (think Lua)

Work in progress .. started 3 months ago, but thinking about it since 
years

just wait for the end of the presentation.

Red language features tour

- Syntax is strongely inspired by REBOL

semantic rules: most of REBOL

- Type system

-- Rcih, most of REBOL types

just an embeddable core into other environments, or will some GUI 
be possible later too? Also - will concepts like 'parse be available? 
networking (and other) ports?

-- New types as pluggable modules (literal form accessible)

-- type inference , when possible

-- type mismatches caught at compile-time instead of runtime

@Pekr parse network ports, yes. GUI later

- First-class functions and HOF support

- Meta-programming support (JIT-compiled code)

REBOL features not supported by Red

- Too "abstracted" code

- Dynamic word binding

Red Architecture Overview

Red Memory Model

- Thread-local memory allocation

-- arrays of 128 bit cells

- Possiblity for shared immutable data structures

- Garbage collector

-- Compacting collector

-- stop-the-thread GC model
