Re: [racket] have built a symbol, now need the value of the id represented by the symbol

Could you use a dictionary (e.g., hash table) instead of `define`s by any chance? Then you would not need `eval` but only `dict-ref`, which is way less problematic. Laurent On Tue, Feb 18, 2014 at 9:54 PM, Geoffrey S. Knauth wrote: > Our local community has a funky tax form not handled by the b

Our local community has a funky tax form not handled by the big tax prep vendors. So I rolled my own with Racket. It outputs LaTeX so I have something to submit all ready. Well it would, except I have goofed something up. I'm eval'ing a symbol (probably incorrect). The symbol comes not from

There has been so much spam for s long. I am constantly removing it. (You may recall discussions on this mailing list years ago about installing a captcha. Apparently the captcha no longer works.) Robby On Tue, Feb 18, 2014 at 6:41 AM, Neil Van Dyke wrote: > Any chance we can use the n

[racket] turn off planet bug tracking system?
