    Not sure if this counts as a "redirection to file":
    use strict; use warnings; open WR, '>', 'file.out' or die "Can't open WR for writing: $!"; print WR foo(); close WR or die "Can't close WR: $!"; sub foo { return 'FOO'; }

    write a wrapper-sub of same name and use select to set the default filehandle for output.
