Got to love this if u've heard the real song

Another Glitch in the Call
(Sung to the tune of a Pink Floyd song)

We don't need no indirection
We don't need no flow control
No data typing or declarations

Chorus:

All in all, it was, just a pure-LISP function call.

If you don't know, the real song is,
Another brick in the wall..
