Subject: 28.1; incorrect indentation level in CPerl mode
Date: Thu, 15 Sep 2022 15:37:00 +0200

Open the following test.pl file with "emacs -Q":

# -*- mode: cperl -*-
# Type TAB on each line.
{
print "",
"",
foo::bar(),
"";
}

and type TAB on each line of the block. I get the following result:

  print "",
    "",
    foo::bar(),
      "";

The last line is indented too much (6 columns instead of 4).

If I replace "foo::bar()" by just "bar()", the indentation is correct.

Yup.  I've now fixed this in Emacs 29.
