Geoff argues that the use of extensible languages leads to unreadable
code for anybody but the author. I agree, but the same seems to happen in
languages that do not include that kind of abstraction mechanisms. It
happens in the form of programming idioms. Most programmes have their
little tricks, that are hard to understand, or does something "dirty", 
and while I do not have to learn the abstracted formalism, I have to
learn to recoqnize certain pieces of code, or data as being related in
a very special way. Some examples from different languages is
In Basic you can not have array of record, but then one just make
an array of each primitive type involved, and remembers that the arrays
are really just one structure.
In prolog someone uses difference lists, which is not normal lists, and
can not be used as such, but you must know that when you read the program.
In Pascal variant record are used to implement soft typing.
And one can go on. All these little things differ from person to person, 
and is one of the things that makes it difficult to read others programs,
even if it is not an extensible language.

Unfortunately it seems like there is no easy way out of this mess. 
I am personally in favor of ext. lang. but know the problem of readability,
and yes I have tried to use some one elses dictionary in forth, and know what
you mean.
