World: r3wp

Update!


I'm implementing support for cyclic series in World these days. My 
initial research about freeing memory taken by cyclic series made 
me realize, that it'll hit performance, if every block and paren 
freed is being tested for cyclic references. So I'll implement a 
FREE mezzanine written in World, that can free such structures. This 
lead me to molding such structures, which is only partly implemented 
in current version of World and copying such structures. Those functions 
will be mezzanines too, as it's much easier to write the code in 
World than in C. So some C code will be removed in next release, 
but we'll have some more World code instead.

Btw. COPY is by defauit deep in World (contrary to REBOL), and World 
will support deep copying of cyclic blocks, which gives a stack overflow 
error in REBOL.

no cyclic error in R3 IIRC (it was fixed in some alpha).

In one of 114 alphas :-)

Maxim, the fix was requested for R3 but not yet implemented, or planned.

hum... strange I feel like it was fixed, since at some point, R3 
coudn't make objects which I required, then, when Carl did the whole 
copy/make makeover, I was able to start using R3 because of deep 
copying issues being resolved ... maybe it was not completely fixed.

I don't think that was about cyclic structures

yes.. definitely but I think Carl may have only fixed it for cyclic 
Objects references.
