Inventing a new syntax won't fix the problem. There is no @image array around.

    Inventing a new syntax won't fix the problem. There is no @image array around.

    So whats the answer ?

    If I had perlmagick I would check if .pdf pages are treated like an image sequence, seems perfectly plausible thing to try

      Sure, you could try to access $foo[42] if only $foo but not @foo is declared. But that won't help you at all: Perl will give you a runtime error with strict enabled. Without strict, perl will just pretend that $foo[42] exists and is undefined.

      >perl -MData::Dumper -e 'print Dumper($foo[42])' $VAR1 = undef; >perl -MData::Dumper -e 'my $foo="bla"; print Dumper($foo[42])' $VAR1 = undef; >perl -MData::Dumper -Mstrict -e 'print Dumper($foo[42])' Global symbol "@foo" requires explicit package name (did you forget to + declare "my @foo"?) at -e line 1. Execution of -e aborted due to compilation errors. >perl -MData::Dumper -Mstrict -e 'my $foo="bla"; print Dumper($foo[42] +)' Global symbol "@foo" requires explicit package name (did you forget to + declare "my @foo"?) at -e line 1. Execution of -e aborted due to compilation errors. >
