I'd lean towards not making the proposed change, as it stands.

Perhaps, for the sake of consistency, we should allow buffer names in
either none or all buffer-related functions.  But the only example given
so far is `get-buffer', and I don't really see how we could possibly
disallow using strings there.  Thus, it's not very convincing.

If anyone is interested in making a better case for this change, a
single example is not enough.  I'd suggest starting with a review of
what we have now, for example something like `M-x apropos-function RET
^buffer- RET'.

Without such a review, I don't really see that we have grounds for
making any changes here.  So I'm tagging this bug "moreinfo".

It's very easy to get the buffer from its name.  You could do

  (buffer-size (get-buffer BUFFER-OR-NAME))

So I wonder whether it is worth our while to convert more functions to
accept both buffers and names of buffers.

Stefan, WDYT?

Hello,

The current signature of #'buffer-size is:

    (buffer-size &optional BUFFER)

It can only handle actual buffer objects as the argument. Could it be
made to accept the buffer name as a string as well? So that it's
signature would become:

    (buffer-size &optional BUFFER-OR-NAME)

Other functions, like #'get-buffer already do this.

Thanks,
--
