File "untitled text 2"; Line 21: Name "main::b" used only once: possible
typo
File "untitled text 2"; Line 18: Can't use string ("array0") as an ARRAY
ref while "strict refs" in use
yeah I can clean that up with
my $fred = 'one,two,three,four';
my $a = 0;
no strict 'refs';
@{"array$a"} = split ',', $fred;
foreach my $b(0..3) {
print ${"array$a"}[$b] ."\n"
}
so as to get the output
one
two
three
four
All of which drives me back to the question - why did we
compel ourselves to have to insert the
"no strict 'refs';"
given the quandery:

why take the convolutions???
What have we added to the long term maintainability of the code
by carbuncling it like this????
Why not compel the author down the road to understanding
how to do good data structures???
