A syntax/perl.vim syntax highlighting file for Vim that highlights 'property'.
Overwrite your existing syntax/perl.vim file, it should be in the vim runtime
directory.
If you can't find this directory you can open vim and type the following
command:
:echo $VIMRUNTIME
or do it from the shell:
vim -e --cmd 'echo $VIMRUNTIME' --cmd 'q!'
if all fails you can always fall back to:
locate perl.vim
