Fair point but I didn’t use the comma because I was golfing. I did it because it was a one-liner that might be retyped and I didn’t want confusion between braces and parens when they’re being eyeballed in the default #Mastodon proportional font (Roboto) or worse.

in reply to Mark Gardner • • •@lkundrak But if you wanted to be cute like @nedbat’s #Python example, the #Perl one-liner is:
perl -MList::Util=sum -E 'say sum map $_ ** 3, 2..9'

in reply to Mark Gardner • • •@mjgardner @lkundrak It may "waste" a character but i'd always write that as
map {$_**3} 2..9
because the braces make the deferred nature of the map expression really obvious. The comma form is way too subtle for casual users.
