I use the for...each construct a lot in my VBA programs. However, that's
because I can iterate through objects. For example:

dim tbl as Table
for each tbl in ActiveDocument.Tables
   '... manipulate the data
next

Since Euphoria doesn't have objects, I don't see how this would be more
useful than what's already available.

for each x in 1 to 50 do
    ?x
end for

Although it would work for iterating through sequences...

sequence s
s = {1,2,3,4,5}
for each x in s do
    ?x
end for

Do any of the OOP libraries out there use this construct to loop through
objects in a class/library/whatever?
