Ladislav:
Rebol differs from human languages in some respects. One of them
can be found comparing Rebol Values vs. Human Values (see
http://www.geocities.com/lmecir.geo/evaluation.txt). This may be a
surprise for both experienced and inexperienced programmer,
because that fact is hidden in other programming languages to some
extent. Another difference can be found comparing the behaviour of
Rebol (CQSB/DRP) functions with the behaviour of their Pure CQSB
counterparts (see
http://www.geocities.com/lmecir.geo/contexts.txt). A set of the
differences can be found studying the behaviour of code -
modifying functions like Repeat, Make Object!, Use, Foreach, ...
The latter difference can be considered a bug, of course, but it
is present in Rebol nowadays.
My personal point of view is, that my previous experience with
other programming languages helped me to understand Rebol and
appreciate its advantages.
