Subject: [sv-bc] Can randomize() be called in a constraint

File this under "customers do the most amazing things". Is it legal to call the randomize function in a constraint? 

class A;
  rand int i;
  RandStuff stuff;
  constraint c { i == stuff.randomize(); }
endclass

This seems to violate the "no side effects" rule.  Not to mention that declaring "stuff" as rand would have done this automatically.

Thanks!
