I agree that it would be a good idea to have tr1 and std be true to the 
respective standards.  It seems like it would be very possible to have 
one representation that would serve both standards with very little 
pain.  There would be some mechanism to support the two as appropriate.  
It actually looks like someone did this with the tr1_impl directory and 
the std headers including from there.  I didn't see in any of the three 
regex headers where certain features were allowed from tr1 and not std 
or vice versa.  Maybe when std is more ... std there can be switches in 
the impl to allow differences:
#ifdef INCLUDE_AS_TR1
#else
#endif

About this separate math function standard.  Where would that be?  I'd 
like to check it out.  Also, is there a TR2 brewing somewhere?  All I 
see is the RFP.
