In which instances do you have to approach a pedestrian crossing with particular care?

Drugs and Alcohol

How is the intoxicating substance in hashish broken down by the body?

• Unevenly over an indeterminate period

In general, how long does it take before an alcohol level of 1.0 per mille (100mg/100ml) is cleared from the blood stream?

• 5 hours
• 10 hours
• 1 hour

A Primer on Ruby Method Lookup

Method lookup is a simple affair in most languages without multiple inheritance. You start from the receiver and move up the ancestors chain until you locate the method. Because Ruby allows you to mix in modules and extend singleton classes at runtime, this is an entirely different affair.

I will not build contrived code to exemplify the more complicated aspects of Ruby method lookup, as this will only serve to confuse the matter. If you are having trouble following method lookup in your own programs, it is not because Ruby has strange rules (it does), it is because your code is too tangled.

When you pass a message to an object, here is how Ruby finds what method to call:

1. Look within singleton class
