Even not. A piece of surealism, a=1 being written in scilab.ini:

Startup execution:
   loading initial environment
Warning : redefining function: head_comments           . Use funcprot(0) 
to avoid this message

This is alpha version: avoid using in production
but please report any problem at http://bugzilla.scilab.org.
Thank you!

--> a
a  =
     1.
--> clear a
--> a
a  =
     1.

--> a=2   // overwritable?!
a  =
     2.        // it looks that yes!
--> a
a  =
     2.       // not just a display issue..

--> clear a   // the last experience that should not be done...
--> a
a  =
     1.That's a ghost!!

--> a*2   // what should be expect: 2 or 4?
  ans  =
     2.

Any confirmation welcome.
