Hi all, I'm working through the book Head First C# (and it's going well so far), but I'm having a lot of trouble wrapping my head around the syntax involved with using the "this." keyword. Conceptually, I get that I'm supposed to use it to avoid having a parameter mask a field of the same name, but I'm having trouble actually tracking ...
Although a subversion repository is like a time machine where nothing is ever deleted. i still find myself reluctant to totally 'svn delete' things from my codebase if i think i might want to search for it at a later date.

I'm a little confused by how keyword accesses seem to behave in Clojure when they are evaluated at macro expansion time. The following works as I expect: (def m {:a 1}) (:a m) => 1 However the same keyword access doesn't seem to work within a macro: (def m {:a 1}) (defmacro get-a [x] (:a x)) (get-a m) => nil Any idea what is goin...

Here is an example: Keywords can be "first name: " and "last name: ". Now I want to parse: "character first name: Han last name: Solo" into { "first name: " => "Han ", "last name: " => "So...
