15:24 flying_rhino: this may come of as a dumb question, but I was wondering about Racket parethesis coloring. None of color schemes Racket is offering (winter spring shades of grey etc) suit me. One of the problems is that none of the schemes color more than 4 layers. Can I just make my own list of colors and make that my pharenthesis color scheme?
15:27 flying_rhino: I would like to have about 8 or so nested layers
15:29 flying_rhino: Another neat thing would be (but I understand it would take some programming) for text to change color for maximum contrast in every layer

16:54 Znudzon: How i can break loop in racket ? (for loop for example)
16:55 jonrafkind: make an escape contiunation around the for loop and invoke it when you want to break
16:55 jonrafkind: (let-ec break () (for ... (break))
16:58 Znudzon: great idea . Thank you

17:18 jonrafkind: oh wait its not related to gc time.. i misread
17:20 chandler: hm. summing up to 2^24 shows a factor of 5 overhead on my system
17:21 chandler: That holds true at 2^26 too.
17:27 Znudzon: So its very unefective right ?
17:28 chandler: Are you optimizing for speed?
17:30 Znudzon: i need only a fast string manipulations . Thats all.
17:30 stamourv: Znudzon: If your loop only does a single addition, yes. If it does anything interesting, you won't notice the overhead.
17:33 asumu: Or if you want to do a fast loop, just use recursion.
17:34 jonrafkind: you can use (let loop ...) for more control too
17:34 stamourv: Better yet, try the nice way first, then profile, and if it's too slow, do something less nice, but faster.
17:34 asumu: (add1 stamourv)
17:35 asumu: Well, I don't know if let/ec + for is the "nice way" or not though.
17:35 stamourv: I find it nice.
17:35 jonrafkind: you use let/ec?
17:35 stamourv: I do.
17:35 jonrafkind: usually i just use let loop when I need that, but I guess I could use let/ec instead
17:35 stamourv: When I need early exit, etc.
17:36 jonrafkind: let loop is sort of a pain
17:36 stamourv: These days, I pretty much only use let loop when I have a really funky iteration pattern.
