Ka'rlis Gobleja mentioned this to Francois Piette:

Actually, you can.  When you specify the explicit type of a constant it is 
called a "typed constant" and is treated like a global variable with local 
scope.  It can be changed during the duration of the program.
I didn't invent it and don't necessarily agree with the way it is 
implemented, but there it is.
