[racket-dev] Minor inconsistency in stepper interface: which way would be right?

2012-07-26 Thread John Clements
Right now, the stepper and the ordinary interactions window disagree in one minor detail (well, one that I know about…): In the stepper, test cases (e.g. (check-expect (+ 3 4) 7)) reduce to a boolean, and leave a printed boolean value in the list of results. In the interactions window, though,

[racket-dev] sequence syntax for (mlist #t #f …) ?

Reality check before I do something dumb and re-invent the wheel: I often want to write a for loop where the first element is treated specially. In such cases, it would be nice to have a sequence that had a #t and then an infinite number of #f's, so I could write (for ([s my-sequence] [first?

I see that rackunit's check-= handles real numbers only, since it uses abs on the difference between the two. I want to use it on complex numbers, and it would seem that changing 'abs' into 'magnitude' would not change the non-error-signalling behavior, and would allow its use on complex
