B is a block of value: ** Script Error: Out of range or past end
** Where: ?
** Near: mold :value
>> ?? b
** Script Error: Out of range or past end
** Where: rejoin
** Near: mold name: get name
If you remember the old thread on this subject, they have also not uniform
behaviour:
1) safe
2) error!
3) rebol crash
All this lead to very hard to find and debug bugs.
Uh! i discovered this:
>> mold/all b
== "#[block![]2]"
useful for sameness?
