(cperl--basic-identifier-regexp) and many other variables:
defining regular expressions for basic Perl constructs.
(cperl-imenu--create-perl-index): This function has been
completely rewritten, keeping only some parts of the output
formatting. It now recognizes a lot more package and
subroutine declarations which came since Perl 5.14: Packages
with a version and/or a block attached, lexical subroutines,
declarations with a newline between the keyword "package" and
the package name, and several more. This version also
correctly separates subroutine names from attributes, does no
longer support "unnamed" packages (which don't exist in Perl),
and doesn't fall for false positives like stuff that looks
like a declaration in a multiline string.

explicitly calls a function of CPerl mode.
