2.2 Coding conventions

• We use accessors (getters and setters) to access instance variables instead of direct random access
• There is a point at the end of each method
• There is no point at the end of a block "[xxx]" instead of "[xxx.]"
• All variables are named in lowerCamelCase -> aFancyVariable
• All comparison operators (ifTrue, ifFalse, ifNil) stand in a separate line
• There is no space between method name and method code
• There is space between local variables and method code
• Blocks with local variables have their expression starting on the next line
• Blocks with local variables have their local variables decleration between white spaces
• Cascades have their receiver on a single line above all messages
• Messages in return over 2 lines are indented with an additional indentation
