Vim for Perl developers

Even more Vim goodies : Leonid Mamchenkov posted some clear and simple instructions about Perl programming with Vim. Most of it covers the scripts for Perl on vim.org, but it listed some nice vim settings I never knew about (eg the listchars option for vertical indentation).

Only thing I miss from a modern IDE (eg Eclipse with the EPIC plugin) is the option of showing command definitions (foreach, confess, split, ...) with a function key. You can summon Perldoc from Vim, but that does not cover function and statement syntax. Can someone provide any clues ?
