This does not seem to work. I tried the following with emacs -Q 

   (setq abbrev-mode t)
   (define-abbrev-table 'my-abbrev-table '(
      ("success"         "success again")
      ("try."            "try again")))
   (abbrev-table-put my-abbrev-table
                        :regexp "\\<\\(\\w+\\.?\\)\\W*")
   (setq local-abbrev-table my-abbrev-table))

success expands as success again.
try. does not expand.

Strange enough, If I try to make a new expansion for "try." with C-x a i l, 
it says that I am trying to overwrite the "try. -> try again" expansion, but 
there is still no expansion. What am I doing wrong ?

I am running "GNU Emacs 23.1.1 (i486-pc-linux-gnu, GTK+ Version 2.16.5) of 
2009-09-14 on raven, modified by Debian"
