Greenspun's Tenth Rule of Programming is a common aphorism in computer programming and especially programming language circles. It states:

Any sufficiently complicated C or Fortran program contains an ad hoc, informally-specified, bug-ridden, slow implementation of half of Common Lisp.

The questions are,

1) Would you consider this to be true of Perl interpreter? Only objective arguments please (e.g. which features of Common Lisp are implemented within the interpreter)

2) Independently, does there exist a Lisp (or at least a n ad hoc, informally-specified, bug-ridden, slow implementation of half of Common Lisp) implemented entirely in Perl?

Why does Paul Graham advocate Lisp? Why did ITA Software choose Lisp over other High Level languages?

Lisp obviously is an advantage for the AI stuff but it doesn't appear to me that Lisp is any faster than Java, C#, or even C.
