Insert a tab or call a function

Hi, I'm trying to write a small function that is called when I press tab
key and checks if current line is empty; if it is, it should insert a
tab, and if not, it should call two other functions. Here's the example
of what I came up with, which does not work right:

function! DoTab()
if match(getline('.'), '^\s*$') != -1
call feedkeys("\<tab>") | return ''
else
call CloseMenu()
call feedkeys("\<c-r>=TriggerSnippet()\<cr>") | return ''
endif
endfu
ino <silent> <tab> <c-o>:call DoTab()<CR>

CloseMenu is another function I have that closes a popup menu if it's
open, TriggerSnippet is a snipmate function that expands current
snippet.


Thanks! -ak
