01:09 jonrafkind: whats the $ for

10:23 samth: rudybot: (struct foo (x y z) #:mutable)
10:23 rudybot: samth: your sandbox is ready
10:23 rudybot: samth: Done.
10:23 samth: rudybot: set-foo-x!
10:23 rudybot: samth: eh?  Try "rudybot: help".
10:23 samth: rudybot: eval set-foo-x!
10:23 rudybot: samth: ; Value: #<procedure:set-foo-x!>
10:23 samth: RackN00b: that makes the whole struct mutable
10:23 samth: you can also do this:
10:24 samth: rudybot: (struct bar ([x #:mutable] y z))
10:24 rudybot: samth: Done.
10:24 samth: rudybot: eval set-bar-x!
10:24 rudybot: samth: ; Value: #<procedure:set-bar-x!>
10:24 samth: rudybot: eval set-bar-y!
10:24 rudybot: samth: error: reference to an identifier before its definition: set-bar-y! in module: 'program
10:24 RackN00b: Which sets only the value of x as mutable?
10:24 samth: that makes just x mutable
10:25 RackN00b: Cool. Any input on my approach: I'm writing a basic Simon game. I need to store the state of the system and individual games - would mutable struct be better/worse than other mutable variables?
10:25 samth: RackN00b: a mutable struct seems sensible
10:26 RackN00b: samth: Sweet. thanks. Man, these assignment we're getting as so vague in their descriptions! I have code that works perfectly under all test conditions I can think of but it still seems to fail the submission tests! Frustrating :P

10:30 RackN00b: samth: I'm clearly doing something wrong here:
10:30 RackN00b: (struct state (state score) #:mutable)
10:30 RackN00b: (define global-state (state 'played 0))
10:30 RackN00b: global-state gives me as value #<state>
10:31 samth: that's right
10:31 RackN00b: what's #<state>
10:31 samth: that's how opaque structures are printed
10:31 samth: that's the name of the structure
10:31 samth: if you want it to print the elements, try this:
10:31 RackN00b: So I'd have to set it to transparent if I wanted to see the values?
10:31 samth: (struct state (state score) #:mutable #:transparent)
10:32 RackN00b: Benefits/drawbacks of transparent vs opaque? It doesn't protect what's stored in the structure, does it?
10:37 (quit) realitygrill: Read error: Connection reset by peer
10:37 samth: it means that other clients can reflectively access your structure instances
