yasnippet insert file name

[Fabian Braennstroem <f.braennstroem@gmx.de>]

Hi,

    I just saw yasnippet and wonder, if it is possible to do
    filename completion as well!?

    A simple:  filename ${1:`(insert-filename)`} does not
    work:

    filename (error in elisp evaluation: Wrong number of
        arguments: (lambda (fn) "Use filename completion to
            insert a filename into current buffer."
            (interactive "FFilename to insert: ") (insert
                fn)), 0)
     
    Would be nice, if someone has a suggestion.

Greetings!
 Fabian
