Your problem might not be, but it all derives from that.

I should have added in my last reply that if you want to investigate
field splitting, and how it works in various cases, use the expansion
of a simple variable
x=whatever
IFS=something
echo $x
or better:
args() {
printf '#=%d' "$#"

But thank you.

Hello again.
I am deeply sorry, but i have one more difficulty that i fail to
explain to myself. It *could* (small, very small case) be that
this time the incorrectness really is on the side of bash.
This script (do not care for the commented, they are great)
a() {
echo $#,1="$1"/$1,2="$2"
P.S.:
the full test (proof, as bash is the example i compare against)
script is this:
# proof {{{
a() {
b() {
echo "b=$# 1<$1> 2<$2> 3<$3> 4<$4> 5<$5> 6<$6> 7<$7> 8<$8>
9<$9> 10<${10}> 11<${11}> 12<${12}> 13<${13}> 14<${14}> 15<${15}> 16<${16}>
17<${17}> 18<${18}> 19<${19
