With his background in integrated circuit design and digital signal processing, he has a fundamental understanding of hardware systems and the software that runs them. Here's a toy example:

> inputs = list(1, 2, 4, -5, 'oops', 0, 10) > for(input in inputs) { + print(paste("log of", input, "=", log(input))) + } [1] "log of The new behavior simply creates the value attribute. print "result is", result ...

print(inst) # __str__ allows args to be printed directly, ... # but may be overridden in exception subclasses ...
