I suggest item US16 under VI. Declaration and Syntax aids for Generic
Programming be revised to state, "Useful to ensure .. that two or more
dummy arguments have the same type."  That is, I do not see anything
in the proposal that restricts the use case to "two dummy arguments"

Also, why is US23 "BITS data type" under "Incomplete or Undecided
Features"?  Keeping in mind M218 paper 19-159 and its references,
particularly 07-007r2,pdf, why would "BITS data type" not be viewed as
anything other than a complete feature, at least for the purposes of
J3 list for consideration by WG5?  Also from J3 perspective, why would
this be "undecided" at this stage given the feature made it all the
way to 07-007r2 draft toward Fortran 2008 standard with past support?
If the response is simply "process" that this feature hasn't again
gone through the process of a repeat paper submission(s) with use
cases, formal specifications, then formal requirements, then syntax
and review and votes and what not, what does J3 have in mind to fast
track Fortran feature items which have already been developed
previously such as the "BITS data type"?  What has changed with bits
in the world of computer science and the Fortran standard since 2008
that suggests reinventing this wheel?

Thanks,
