Re^2: Best practice for sychronous output handling using open3()?

gensym (in Symbol) returns a ref to a new glob every time it's called.

my $cmdin=gensym;
my $cmdout=gensym;
my $cmderr=gensym;
open3($cmdin, $cmdout, $cmderr, $cmd);
[download]

is like

my $cmdin=gensym;
my $cmdout=gensym;
my $cmderr=gensym;
open3(\*IN, \*OUT, \*ERR, $cmd);
[download]

without the risk of conflicting names.
