[J3] J3 letter ballot reminder

[Daniel C Chen]

The following Fortran interpretations are being balloted:

Yes  No   Number    Title

-C-  ---  F18/007  Problems with C_FUNLOC and C_F_PROCPOINTER being PURE
-Y-  ---  F18/015  Example in C.6.8 is wrong
-Y-  ---  F18/019  PURE and default initialization
-Y-  ---  F18/023  CLASS(*) ambiguous operator overloading
-Y-  ---  F18/024  CFI_setpointer with result a deferred length character
-Y-  ---  F18/025  Is component initialization an attribute?
-Y-  ---  F18/026  C_SIZEOF argument
---  -N-  F18/027  CO_BROADCAST with allocatable component
-Y-  ---  F18/028  Specification inquiry
-Y-  ---  F18/029  Type of main argument of CO_REDUCE
-Y-  ---  F18/030  CO_REDUCE/REDUCE OPERATION with coarray argument
-Y-  ---  F18/031  CO_BROADCAST with polymorphic argument
-Y-  ---  F18/032  CO_BROADCAST and pointer components

F18/007:
I can't see the point of the new constraint why the argument of C_FUNLOC
must be pure if C_FUNLOC is referenced in a pure subprogram. I understand
if the impure result of C_FUNLOC itself is called, it will violate the
rules, but just referencing C_FUNLOC seems OK. Moreover, since
C_F_PROCPOINTER is no longer a pure routine, it seems it is even less
possible that the result of C_FUNLOC can be referenced in a pure
subprogram. I understand it probably makes referencing a C_FUNLOC with an
impure argument in a pure subprogram pointless, but it still doesn't seem
break anything either.

F18/027:
This requires deallocation and reallocation on top of assignment to every
nested allocatable components. It is not going to have a good performance
as it is intended to do. I think we need a bit more discussion on this one.

Hi folks, A reminder that the letter ballot deadline is in a little under
three days. So far, I’ve only seen votes from Steve Lionel and Van Snyder.
