1512. Obtained by grepping the src directory of Qt 4.8.0, so the 
number includes duplicates, comments, etc. I think that even if 
the actual number is lower by an order, some 100 types using 
mutable still do not qualify for 'extremely scarce'. If I have 
time (which is unlikely), I will probably analyse the codebase 
for the actual number.
