    Yes...it worked for me up till the latest perl.  I was surprised.

The man page documents usage as:

       "Term::Size::chars" returns the size in units of characters, whereas
       "Term::Size::pixels" uses units of pixels.

       In a scalar context, both functions return the first element of the
       list, that is, the terminal width.

       The functions may be imported.
