My issues with Modules

In researching topics for RailsCasts I often read code in Rails and other gems. This is a great exercise to do. Not only will you pick up some coding tips, but it can help you better understand what makes code readable.

A common practice to organize code in gems is to divide it into modules. When this is done extensively I find it becomes very difficult to read. Before I explain further, a quick detour on instance_eval.

You can find instance_eval used in many DSLs: from routes to state machines. Here's an example from Thinking Sphinx.

Drink Positive

Mezcal Bone Crusher

Here is a variation of a Bone Crusher, a drink originally inspired by acclaimed cocktail writer David Wondrich's Bone cocktail made from rye whiskey, lime juice, sugar and a few dashes of Tabasco.

Here, this spicy, earthy, smoky drink was made from Del Maguey's Single Village Mezcal (Minero), El Tesoro Reposado Tequila, demerara sugar simple syrup, lime and Tabasco.
