A clarification is needed: if $x is a "simple scalar variable", then what is ${fh.$FILE}?

    A symbolic reference?

    map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

      I was under the impression that in this case brackets around a variable name are just to clarify things and $x was a synonym to ${x}. Is ${x.$y} a special case? https://perldoc.perl.org/perlref#Not-so-symbolic-references calls that a not-so-symbolic reference! Tomorrow I will post a question as I am still confused on the boundaries.

      thanks

        JSAWS seems to be running without strictures (and warnings?) enabled, so the OPed code seems to be using honest-to-goodness symbolic references.

$n = 99;

${ foo . $n } = 'zot';

print $foo99;

zot

        This is the general case in these circumstances (and one of the motivations for the creation of strict).

        Update: The { } brackets in ${ foo . $n } are required for disambiguation. The statement
            $foo . $n = 'zot';
        produces a very different result.
