This has the affect you want, at least for the example supplied:
print join "\n", 1..3, "\n";;
1
2
3

I think that's three people saying "Give it up, Keith; she's dead, buried, forgotten, and even the life insurance money's all been drunk up." All righty, then - thanks, all you wise Perl Monks!

It's not a statement modifier, but it is a "loopy thing".
print( ( map { "$_\n" } 1 .. 3 ), "\n\n" );
...but why?

'K, I'll try to say it a different way: is there a way for me to use a
statement modifier like print "$_\n" for 1..3 and add
something to the end of it, like an extra newline, that doesn't mess with
the loop but just gets printed after it? I've tried parens, brackets,
commas, the dot, and mayonnaise with ketchup smeared nice and even, but
none of it works (and some is pretty messy.) Is there a way to do it?

Yeah, statements are constructs like:
if ($foo) {print "Hello"};
package Foo 1.2.3;
use Hello;
{ 1 }
next if $bar;
None of those can receive a "statement modifier".
In fact, if you inspect perly.y you'll see that expressions are modified:
sideff : error
| expr
| expr IF expr
| expr UNLESS expr
| expr WHILE expr
| expr UNTIL iexpr
| expr FOR expr
| expr WHEN expr
;
with sideff one of the many forms of statements.
If you're going to reply with irrelevant snobbery, please aim for the middle of the bowl instead of peeing all over the stall.
And think what exactly is a "statement" in Perl! | [reply]

Interesting! Hence, a statement modifier turns an expression in a statement. Didn't expect this.
BTW, my comment was not intended as snobbery, but because I concluded that statement modifiers are never part of a sub-expression (as the OP wanted to use them). In any case, your comment is appreciated.
