Eof

A language that unless your careful it will automatically end the program.

You can see some basics here (Hello World!):

eof not now
eof after eof says Hello World
eof now

Fibiancci:

eof not now
eof make eof create fib as 1
eof make eof create i
eof think eof for eof i in eof 100 eof then
 eof says Fib + eof remember the last known eof value of eof Fib
eof ends this eof
eof now

So in summary you have to continue telling it not to eof until you want it to eof, you don't have to write eof now at all, but if you do it keeps things a bit controlled, right eof?

eof not now
eof says "Maybe"
eof now

Whatever eof.
