+	 * Throws any throwable 'sneakily' - you don't need to catch it, nor declare that you throw it onwards.
+	 * The exception is still thrown - javac will just stop whining about it.
+	 * 
+	 * Example usage:
+	 * 
+	 * <pre>public void run() {
+	 *     throw sneakyThrow(new IOException("You don't need to catch me!"));
+	 * }</pre>
+	 * 
+	 * NB: The exception is not wrapped, ignored, swallowed, or redefined. The JVM actually does not know or care
+	 * about the concept of a 'checked exception'. All this method does is hide the act of throwing a checked exception
+	 * from the java compiler.
+	 * 
+	 * @param t The throwable to throw without requiring you to catch its type.
+	 * @return A dummy RuntimeException; this method never returns normally, it <em>always</em> throws an exception!
