Ehhrmm, why ? 

This is such a silly restriction that I can't beleive it's in the language. 
Since I don't have my Wirth at the ready, all I can say is that
with a few tens of thousands of lines M-2 behind me, I'm merely 99.99 % sure
that variables are only allocated space ONCE (i.e. in the module where
they are defined, be it in connection with the compilation of the
IMPLEMENTATION or the DEFINITION module).

Since this is somp.lang.modula2, perhaps someone with a PIM2 at hand could
put us all at ease here .....
