[boost] Re: Forward Declaring Headers

For classes in the standard library, wouldn't this have to be provided by the
library implementors? Because they are allowed to add additional defaulted
parameters to standard functions, or to provide additional functions with fewer
parameters in lieu of defaulted arguments, a user could never be certain what
the proper forward declarations would be.  Or did you mean only that boost
headers should have a companion <*fwd> counterpart?
