Possible Screencasts

Please note this is my perception of what was said in the lecture. It may or may not be correct.

Packages

• Explain the basic idea of packages
• Mechanics in Lisp -> how to create a package
• Symbol syntax used (package-name ::symbol)
• Other weird stuff -> #:symbol , : keyword, (symbol-name ...), (intern ...)

Macros

• Basic idea: transformation of source code at compile time
• Back quote, comma, (comma, @)
• Only once evaluation
• Avoiding variable capture
• Pragmatics

Collections

• Operations for mapping
• Search
• Reduce - reducing list to single value
• For lists, vectors etc.
• Simple (equality) operations and high order function versions (?)

Non-standard method combination

i.e. :before :after :around methods

• Syntax for specifying :before :after :around
• Semantics
• Interaction with multiple inheritance
• Examples of use
• Contrast and compare Lisp with AspectJ

Conditions

• Condition classes (simplified class type)
• Separation of raising an error from unwinding the stack
• Coding handlers

Hashes

• (make-hash-table ...)
• :test eql or equal
• (get hash ...) (setf(get hash ...))
• Loop support for iterating over keys and values

Multiple Values

• (get hash ...)
• (values principle-value ...)
