As in C and shell, the ' (apostrophe) format flag is used for​:

  Decimal conversions (d, u, or i) or the integral portion of a
  floating point conversion (f or F) should be grouped and
  separated by thousands using the non-monetary separator
  returned by localeconv(3).

This would make it even easier to perform the common task of commifying numbers.

I'm not sure I agree with the feature request, but it would be interesting to learn why Perl differs from C and the shell in this regard.

It doesn't really differ from C. The ' flag is not part of standard C.
(I don't know how common this extension is in practice.)

I didn't realize it wasn't part of the C standard. Apparently it is defined as an XSI extension [1]. I did verify that it is supported in C on Linux, OS X, FreeBSD, and NetBSD. Other languages supporting it are Bash, Zsh, and awk.
