You can use the @{[ ... ]} construct. 

$ perl -Mstrict -Mwarnings -E 'my %y = qw{c 3 d 4}; say "@{[%y]}";'
c 3 d 4

The expression can be arbitrarily complex.

$ perl -Mstrict -Mwarnings -E 'my %y = qw{c 3 d 4}; 
> say "@{[join q{;} => map { $_ . q{=} . $y{$_} } sort { $b cmp $a } k
+eys %y]}";'
d=4;c=3

You can use a subroutine.

$ perl -Mstrict -Mwarnings -E 'sub z { reverse @_ } my %y = qw{c 3 d 4
+};
> say "@{[z(%y)]}";'
4 d 3 c
