That sample has several errors (incompatible types in assignment, wrong
order of operands, missing "fun void" in the function declaration).  It
doubt anyone ever tried to run it.

Python is the only common language that I know of where indentation is
important to the compiler.  For other languages it's just a convenience
to make it easier for the programmer to read.  I personally use XEmacs
with the chuck.el that's been posted here a few times.
