Compound assignment doesn't work in the interactive mode

[Night-walker]

(dao) (a, b) = (1, 2)
= ( 1, 2 )
(dao) a
[[ERROR]] in file "code string":
  At line 1 : Invalid expression --- " a ";
  At line 1 : Symbol not defined --- " a ";

Actually it didn't stop working, just never worked in such mode.

Here a and b are automatically declared as local variables, which cannot be used in the following commands. Only global variables can be used across commands in interactive mode, where variables are usually automatically declared as globals.

Apparently we forgot to do the same for variables declared in compound assignments. Will be fixed.
