Re: Inconsistency in Namespace Internal Name Management, Ver 5.1.1

[J Naman]

Almost. Consider:
@namespace "ns"
function ns1(){return 1}
function ns::ns2(){return 2}
function awk::defined_in_ns3(){return 3}
@namespace "awk"
function awkspace4(){return 4}
function awk::awkspace5(){return 5}
==================
Your awk::foo() <==> my @namespace "awk"; function awk::awkspace5(){return
5}
Your foo() <==> my @namespace "awk";  function awkspace4(){return 4}
Your set did not include @namespace "ns"; function
awk::defined_in_ns3(){return 3}
which I think would be:
bash-4.2$ gawk '@namespace "ns"; func awk::foo() {print "hello"} BEGIN {for
(i in FUNCTAB) print i; for (i in PROCINFO["identifiers"]) print i}' | grep
foo
foo
awk::foo
The @namespace "not_awk"; func awk::foo() is illustrated by Chap 15.7
Namespace Example # ns_passwd.awk
@namespace "passwd"; function awk::getpwent()
which would give getpwent and awk::getpwent()  # I believe
Okay?
