Yes, perpetual ';' or '}' or 'end'. Tons of ';'.

And me personally hates to see something like to:
                  
                       end;
                     end;
                   end;
                 end;
               end;
             end;

No, just more clear code.

My main thought was and is: in basics,  5..6  different 'exits' are just for 
struggle with its own, basic's, 'goto'.

Strange design. I know, it is for compatibility with older versions,
but strange anyway.
And I do not want an inner war of Euphoria key words.

Good Luck!

I'm out of town now, sorry.
