Dear All,

the following document recommends not using semicolon (;) delimiter in Mata:
"We recommend that you do not use Mata when Stata is in #delimit ;
mode. Mata will not mind, but you will confuse yourself."
              http://www.stata.com/help.cgi?m2_semicolons

Why does Mata complain in the following example? (see
"mata_des_bug.do" below). Who is confused, me or Mata?
(happens for mata des followed by ; and for mata mosave followed by ;)

Thank you,
   Sergiy Radyakin



/* --- begin of mata_des_bug.do ------ */

   /* 1. This part works */
   #delimit cr
   mata mata clear
   mata
     void function foobar() {
       1
     }
     mata des
   end

   mata: foobar()

   /* 2. This part does not work */
   #delimit ;
   mata mata clear;
   mata;
     void function foobar() {;
       2;
     };
     mata des ;
   end;

   mata: foobar();
