do is just a glorified eval `cat FILE` mechanism.

... without creating a sub-process and running cat, of course.

    of course that's why I said "mechanism" and linked to the docs.

    do "./stat.pl" is largely like

    eval `cat stat.pl`;

    except that it's more concise, runs no external processes, and keeps track of the current filename for error messages. It also differs in that code evaluated with do FILE cannot see lexicals in the enclosing scope; eval STRING does.
