Mold

What is mold? Can you give me an example?

Mold encloses text in quotes.
    
write %mold.txt mold "some text"
print read %mold.txt
    
The write line above is the same as:
    
write %mold.txt {"some text"}

The IMHO more important MOLD/ALL (/ALL being a refinement to MOLD) serializes REBOL code and data, so you can save it to disk and load it again:
    
>> a: make object! [b: make hash! [] c: 67 d: none]
>> mold/all a
== {#[object! [
     b: #[hash![]]
     c: 67
     d: #[none]
]]}
    
>> probe load mold/all a
make object! [
     b: make hash! []
     c: 67
     d: none
]

Totardo,
    
To add a little to Henrik's example above, you can save and load to a file, for example, like this:
    
a: make object! [b: make block! [] c: 67 d: none]
write %somedata compress mold/all a
probe load decompress read %somedata

The example above works in R3. Compressed data is binary, so for R2, you'd need /binary refinements:
    
write/binary %somedata compress mold/all a
probe load decompress read/binary %somedata
    
More likely, you'd just do:
    
write %somedata mold/all a
probe load %somedata

(That works in both R2 and R3)
