missing the point!

Already proven in the post you downvoted (line 13)

"the post you downvoted"

Nope again. (Update for the slow-to-comprehend: I did not downvote the post you linked to.)

Orly?

So please explain!

$ perl -Mstrict -wE 'my $str = "foobar"; say 1 if $str =~ /{,3}/; say 
+$]'
5.028002
$

(Update perl version added)

update

>perl -Mstrict -wE "my $str = 'foobar'; say 1 if $str =~ /{,3}/; say $
+],':',$^O"

I would guess there's a special case when the brace is the first character in the regex.

$ perl -wE 'say $]; say "Match literal" if "{,3}" =~ m<{,3}> && "x" !~
+ m<{,3}>;'
5.030001
Match literal

$ perl -wE 'say $]; say "Match space" if " {,3}" =~ m< {,3}> && "x" !~
+ m< {,3}>;'
Unescaped left brace in regex is illegal here in regex; marked by <-- 
+HERE in m/ { <-- HERE ,3}/ at -e line 1.
