Hi ROOT'ers, 

I short question: 

  Can "mutable" be used in persistent classes? 

Searching the web pages gives: 

   TParticle - source file
   TListIter - source file
   TList - source file
   TTreeFormula - source file

and they all say something like: 

    //cast const away, fCache should be mutable 

or similar.  So what I want to know is: Is this a ROOT/CINT limitation
or is it a compiler limitation? 

I'm using CVS head as of ~1 week ago on a Redhat 6.2 machine (that is
GCC 2.91.66).  

Yours,
