This is not true at all.

Sorry, not true at all. There really is no trick. Interpolating is
interpolating is interpolating.
When you start ?deeply nesting? and quoting in tables and here documents,
perl will never fail to interpolate unless you don't understand the syntax
and semantics of injecting values into literals.
Perhaps you could post an example, because I am very curious. But taking an
educated guess at the problem you are having, I would say you are talking
about getting CGI.pm's param() function to return in a string.
my( $string ) = you ordered $q-param('quantity') foobars\n;
The quoting mechanism knows nothing about evaluating expressions. That's
what concatenation is for:
my( $string ) = you ordered . $q-param('quantity') . foobars\n;

CGI.pm strange results
Hello,
I am not understanding why I am getting strange data from the my CGI.
Please point out what I have done wrong.
Thanks
