OK. I guess that's currently not possible. I had a quick look in the 
code, the global variable namespace seems to be copied from the parent 
script during execution of the include statement. (In 
ext_include_generate_include() which calls 

So maybe it is possible to take another approach:
Instead of executing sieve_before scripts and sieve_default side by 
side, maybe it is feasible to set the "before-script" as sieve_default 
and include the default personal user script from there if it exists? 
That way global variable inheritance should work, shouldn't it?

Did anyone try this approach? Any caveats? Any security implications?
