# This is the code from my 'There is No Such Thing as Metaprogramming' talk,
# which premiered at the Arlington, VA Ruby Users Group on Feb 22nd.

# will be missing quite an important bit of content (mainly the tracking of
# 'self' while developing the solution, but it still a useful read.

# the code, is completely unuaware of the interpreter. A developer with a
# background in compiled languages would be comfortable looking at this.
