Yeah, your way of evaluating probably works fine. On the other hand, I can do things like this:

use Inline C => 'int square(int x) { return x * x; }'; \C-j
square(square(23)); \C-j

and both statements will be sent to the same Perl. I guess that makes it "more interactive" or something. The real gain is, in theory, in the cross-referencing.

Thanks for pointing out the "readmore" -- I didn't realize that you needed to close the tag before it took effect.
