Is there a way to pass "Time::Piece" object from "localtime" directly as function parameter without using variables $t or $x? 

#!/usr/bin/perl 

use strict; 
use Time::Piece; 

sub time_repr { 
    $_[0]->strftime("%F %T"); 
} 

my $t = localtime; 

print 
    "ref in var OK: ", (time_repr($t)), "\n\n",

    "not elegant: ", (time_repr(do { my $x = localtime() })), "\n\n",

    "error 1: ", eval { (time_repr(localtime)) }, $@ , "\n",
    "error 2: ", eval { (time_repr(\localtime)) }, $@ , "\n",
    "error 3: ", eval { (time_repr(\(localtime))) }, $@ , "\n",
;
