> Is there a simple way to generate unique handles automatically for each element in my array of input files, without typing out a silly array like the @FileHandles shown above?

I'd rather use a hash to hold the %handle per path.

  DB<111> $path='/tmp/path'
 => "/tmp/path"

  DB<112> open $handle{$path},">",$path;
 => 1

  DB<113> $handle{$path}->print("This is File $path")
 => 1

  DB<114> close $handle{$path}
 => 1

  DB<115> `cat $path`
 => "This is File /tmp/path"

This works for me, but plz note that I had to use the normal (and saner) method call syntax for print.

But I have to doubt that you really need to open 100 files simultaneously, maybe you should consider a better algorithm which works sequentially?

HTH! =)

edit

another limitation is that you can't use < ... > syntax for readline

  DB<127> open $handle{$path},"<",$path;
 => 1

  DB<128> ref $handle{$path}
 => "GLOB"

  DB<129> print while (<$handle{$path}>)
GLOB(0x8f19688)
  DB<130> print while (readline($handle{$path}))
This is File /tmp/path
  DB<131> seek $handle{$path},0,0
 => 1

  DB<132> readline($handle{$path})
 => "This is File /tmp/path"

update

anyway looping over the hash fixes all syntactic "anomalies" again

  DB<151> while ( my ($path,$handle) = each %handle ) {
           print <$handle>;
           }

This is File /tmp/path

Just to be sure, no trouble with strict!

  DB<159> ;{ 
           use strict;
           my $path="/tmp/path";
           my %handle; 
           open $handle{$path},"<",$path; 
           while ( my ($path,$handle) = each %handle ) {
             print <$handle>;
           }
           }
This is File /tmp/path
