You are both right.  Johnny is using the formal language definition of
regular expression while 7stud is using the term to refer to particular
programming language constructs.  Most modern regexp libraries allow
for patterns that go well beyond the formal language concept of
regular expressions.

Still, I'm not sure how you would defined nested strings using a single
quoting character: 

"stuff"otherstuff"morestuff"

Is that an example of a nested string or just two strings with otherstuff
inbetween?
