Who Should Attend:
Intermediate Perl programmers and those with some Perl experience and basic familiarity with packages, objects, references, and modules.

We'll expand on the highly successful 'Perl Hardware Store' talks of the past two Perl conferences, but with a more serious bent. The Hardware Store talks introduced powerful programming techniques such as iterators, memoization, and higher-order computation that are drawn from the Lisp and functional programming worlds. In this new tutorial we'll explore these and other techniques in much greater depth than the Hardware Store talks.

Course Outline:

• Recursion
• Dispatch tables
• Caching, memoization, and lazy computation
• Iterators
• Streams and infinite lists
• Higher-order functions: merging, filtering, and reducing
• Higher-order functions: composition
• Functional parsing
• Sideways approaches to object-oriented programming
• Constraint systems
• Control flow alternatives
