Personally, I think that's the desirable behavior, but you should keep 
in mind that this will require the indentation engine to look ahead in 
the buffer and account for the case when there's no text after the 
point, for example.
Suppose the first value function actually has a non-empty body, and 
we're just typing the code for the first time.
Even if we're using a snippet package that inserted "function() {}" for 
us, we will type the important comma after "}" only when the function 
body is written, and then we'll have to go back to reindent the body again.

I think that's acceptable, but that's not how indentation functions in 
Emacs usually work.
