Both routines need an alias (or adverb) so that a newline is automatically appended to the output. I would like to see something like​:

  sprintfn
  printfn

or

  sprintf-n
  printf-n

or

  sprintf-nl
  printf-nl

From @lizmat

Just curious, but what is wrong with "say fmt()" ?

Liz, one reason, i'm ashamed to say, is lack of familiarity with fmt()
(too many years of C/C++ and Perl 5, I guess). The printf family I am
very aware of and am trying to get the docs right. It looks like fmt
can almost piggy back on some of it, though.

I'd prefer to avoid adding two new subs and two new methods for the sake of saving a single character of typing. Since you're writing the format already sticking a \n into it isn't that difficult.

I don't think that works as a justification. The put() is used much more frequently than printf(), so it makes sense to have it as a "\n"-adding alternative to print().
But my main point was that with printf() you're writing the format string anyway, so adding a \n into it is easy, as compared to adding one to print()​:

  put self.meow;
  print "{self.meow}\n";
 
Compare to​:

  printfn "%s", self.meow;
  printf "%s\n", self.meow;

You literally save 1 character of typing in a not the most used subroutine, all for the price of 4 extra routines for developers to maintain and document and for users to remember and debug when they miss the `n` at the end of the sub name.

Just a little humour. Someone thought thought it was worth it to not have
to explicitly add the newline on print, and I feel the same way about
printf.

I respectfully disagree, Zoffix. I used printf in Perl 5, to a file, for
many years writing auto-generated documents, and I would have loved to have
the equivalent of println (is that Java?).

In addition, such a function would reduce code line noise quite a bit IMHO.

Anyway, if we ever get printf for an IO​::Handle, I would like to see
something like I suggested.

I would give up the fmt() routine if necessary to avoid extra maintenance.

I don't like it. Those names don't speak very well for themselves.
On the other hand, adding a \n at the end of the format string doesn't seem to be such a big burden.

If you don't like to reach for your backslash key, say sprintf "..." is also an option.

Cheers,
Moritz

Moritz, that's fine for sprintf, but it doesn't help printf if it ever gets to be a method of IO​::Handle.
