Your latest message, quoted below, leaves me even more baffled about your problem case.

Harking back to my original question, '(w)hy an AoH? Why not simple hash?', I suggest the following approach lends itself to further transformation of the records into a simple hash (using the "value" elements as the keys) of the fields:

#!/usr/bin/perl
use 5.016;
use warnings;
use Data::Dumper;

=head vitoco's msg:

 vitoco says Re Re^2: Move data into AoH The data file happens to be a
+ JSON structure, an array of records, very like an AoH. I know how to
+ manage them in perl, but as text values may have the special chars i
+nside, there was no simple regexpr to parse that.

=cut

# 1055528 

my @arr;
my $recsep = q(,);
while ( <DATA> ) {
  @arr = split /$recsep/, $_; 
}

my $i=1;
for my $record(@arr) {
    say "\t $i: $record \n";
    ++$i;
}

say "\n\n";
say Dumper @arr;
 

=head

vitoco: There are no newlines (I put them to show records), 
ww: So here's data with extra newlines removed but with (from OP) some
+ regex-special characters... namely, the square brackets... which vit
+oco says  prevent writing a "simple regexpr" -- OK, this uses split a
+nd a regular expression (with<b>out</b> any post-5.8 bells and whistl
+es), but the outcome isn't changed.

=cut

__DATA__
[{field1:value1,field2:value2,field3:value3},{field1:value4,field2:val
+ue5,field3:value6},{field1:value7,field2:value8,field3:value9}]

Am I hopelessly off target with respect to your intent? If so, can you explain more clearly for the guy (\me) currently playing 'village idiot'? (Remember, every village needs one.)
