(Redirecting back to the list.)

It's a bit of history from LPC, and others would be better at
explaining than I am, but my understanding is that it derives from the
fact that your whole script is itself a class definition. In fact, you
can actually clone a program by its file name - there's a standard way
to cast a string to a program (or directly to an object), which loads
the script from disk and parses it.

object parsevdf = (object)"parsevdf.pike";

The file "parsevdf.pike" contains a program, by any definition of the
word. According to Pike, it contains the definition of a class - which
means that this class is a program.
