[DGD] Fw: Re: callout cantrip

[bart at wotf.org]

Well, that idea seems to work quite well..

a=2; 
b=0; 
catch { 
  return a/b; 
} : { 
  write(caught_error(1)); 
}


when called causes:

[CAUGHT] Division by zero
Object: /std/user#62, program: /std/user, line 187
 187 receive_message   /std/user (#62)
 182 _receive_message  /std/user (#62)
 675 receive_message   /std/player (#79)
  23 main              /cmds/wiz/eval
  10 exec              /tmp/aidil

Code is in the latest gurbalib distribution and in subversion of course.
