| | If the expression represents the source token stream, then are these
| | meant to be equivalent or different:
| |    A<1+(int)1.0>
| |    A<1+(int)1.00>
| | ?
|

I would answer no.  I think 1.0 and 1.00 are just different spellings
for the same token, much in the same way bitor and | different
spellings for the same token -- although the latter equivalence is
clear from the Standard.
