With the Symbol module, you can use gensym() to create a new, anonymous typeglob. Since that's the customary way to get at a filehandle, you can do something like this, to create an array of anonymous filehandles:
#!/usr/bin/perl -w use strict; use Symbol; my @handles; for (1 .. 2) { my $fh = gensym; open $fh, "test$_"; push @handles, $fh; } foreach my $handle (@handles) { print while (<$handle>); print "---\n"; close $handle; }
In a production environment, I wouldn't use a symbolic reference to a filename like I do in the first loop, but this is just an example.
