I'm missing your point.

If you mean to indicate that interpolation happens inside m//, and  
that $^ is an internal perlvar (with $FORMAT_TOP_NAME as a 'use  
English' equivalent), then it is *not* an empty string.  Here's the  
one-liner to show that...

$ perl -le 'print $^'
STDOUT_TOP
$

But, perhaps I missed your intent.
