so, there's advice qualifiers for DEFMETHOD
and they have "standard combination"
http://www.lispworks.com/documentation/HyperSpec/Body/07_ffb.htm
:around and primary methods can call CALL-NEXT-METHOD can be used to
invoke a less specific method for the class
:before and :after are all always called as a onion with most specific
on the outside
objects similar to structures, but can have "generic" setters and creators
generic methods can have methods with qualifier :before :after :around
that in a way I don't fully understand registers them to be launched
with original function?
- types are complicated, not sure how to look up documentation for it
would they show up in apropos all?
- list formatted types - like array vector can specify type of element,
rank / dimentions
(not sure there's variancy over the element type?)
- clos - similar to structure
for structured you get separate functions to get slots, use setf to set
generalized variables
with classes, I can use generic function to create #'make-instance
and access slots with (#'slot-value instance 'slot-name)
but there could be defined accessor, reader, writer,
and :initarg to name slot to have handle to set value in constructor
now that's a lot
- loops can be "ON" a list, then iterate over structure, and can be BY 'cddr and such
- looping over hashtables seems painful
- during coding didn't think about getting debugger,
couldn't figure out how to do it without BREAK, and in DO loop didn't
see separate frames
- again remembered MAKUNBOUND for if I try to set values during debugger
- characters are # and non-excape, #\a
- i am way to quick to judge pairwise operations from left with #'reduce
- iteration can be actually simple with dotimes, dolist.
i'm quite afraid of #'loop but #'do seems cool and inviting
- key params are after &rest, and get put into &rest in order of call
appearance
- can have closure around same place / generalized varialbe, holy cow
- apply takes list, but can also take several arguments with last one
being a list
(values 1 2 3) at the tnd of funtion fill make funciton return 1, 2, 3
and I can either treat function as returning single value,
or use functions like multiple-value-list or multiple-value-[bind|setq]
to get secodary return values
so not quite like a tuple
arrays have #'array-dimentions and #'array-rank (as a matrix)
and there's cool (row-major-aref my-arr index) for indexing array with
single index, going throug all elements
vectors have literal notation #(1 2 4 1),
they are one dimentional
have :element-type key in constructor, not quite sure how to use that
and we can try to #'coerce list to something else by providing symbol
for type, which we could get from (type-of my-vector)
also literal notation for byte vectors, cool #*110011001
