Re: scope of variables

enum a,b 
while 1 do 
   integer b -- the scope of this variable should be limited to the while 
   b=1 
   ?b 
   exit 
end while 

It is defined already. enum b. Euphoria's scoping does not allow multiple definition but its scoping works correctly. For example:

integer a 
while 1 do 
  integer a 
end while 

That also is an error. Now:

integer a 
for i = 1 to 5 do 
    integer b = 20 
end for 
? b 

That is also an error, i.e. the ? b is used outside the scope of b, thus b is not defined in that instance.
