<p>Next we'll need to have "Keyboard::Improved" to give us keys to represent other mathematical functions such as the integral symbol, the nth root symbol, longhand division symbols, Pi, Sigma, and so on. Seriously, if we're going to nitpick about <code>abs()</code> versus <code>|-5|</code>, we'll have to do away with the entire <code>fn()</code> idiom as applied to the programmers version of mathematical symbols.
