Proposals Discussed at Plenary#
#22 : Default values of optional arguments (https://j3-fortran.org/doc/year/20/20-107.txt)
#157 : Rank-agnostic array element and section denotation (https://j3-fortran.org/doc/year/20/20-113.txt, https://j3-fortran.org/doc/year/20/20-115.txt)
#158 : TYPEOF and CLASSOF (https://j3-fortran.org/doc/year/20/20-114.txt)
#1 : Namespace for modules (https://j3-fortran.org/doc/year/20/20-108.txt)
Interpretation: FORM TEAM and failed images (https://j3-fortran.org/doc/year/20/20-102r1.txt)
Interpretation: Collective subroutines and STAT= (https://j3-fortran.org/doc/year/20/20-104r1.txt)
Interpretation: events that cause variables to become undefined (https://j3-fortran.org/doc/year/20/20-119.txt)
Edits for SIMPLE procedures (https://j3-fortran.org/doc/year/20/20-116.txt)
#146 : Interpretation: allocatable component finalization (https://j3-fortran.org/doc/year/20/20-117.txt)
#157 : Rank-agnostic syntax (https://j3-fortran.org/doc/year/20/20-120.txt). Passed unanimously with minor changes.
#156 : Protected components (https://j3-fortran.org/doc/year/20/20-121.txt). Withdrawn to address conflicting interests.
#160 : Edits for auto-allocate characters (https://j3-fortran.org/doc/year/20/20-122.txt). Passed unanimously with minor changes.
Edits for procedure pointer association (https://j3-fortran.org/doc/year/20/20-123.txt). Passed unanimously.
#157 : Edits for rank-agnostic bounds (https://j3-fortran.org/doc/year/20/20-124.txt). Withdrawn because some edits were missing and need to be added. There were concerns about fitting into the framework of generics later on.
#157 : Edits for rank-agnostic array element and section denotation (https://j3-fortran.org/doc/year/20/20-125.txt). Failed (5 v 7). Missing edits, and disagreement on types vs rank-1 integers, the options need to be explored more.
#157 : Edits for rank-agnostic allocation and pointer assignment (https://j3-fortran.org/doc/year/20/20-126.txt). Passed unanimously with minor changes.
Interpretation: Public namelist and private variable (https://j3-fortran.org/doc/year/20/20-127.txt). Straw vote (0 yes, 8 no, 9 undecided). Passed unanimously with “no” alternative.
Interpretation F18/015 (https://j3-fortran.org/doc/year/20/20-105.txt). Passed unanimously.
This was on the plan but we did not get to it:
#5 : US 27 POINTER dummy arguments, INTENT, and target modification (https://j3-fortran.org/doc/year/18/18-144r1.txt)
#19 : Short-circuiting proposal
