Modules are only imported once no matter how many times the 'import' 
statement shows up. If you really want to re-import the z3 module, try 
doing a 'reload z3'.

think you would have to recompile your Python interpreter to change 
this, and I can't conceive why you would want to be deliberately 
incompatible with everyone else like that.
