I'm trying to extend + to accept a list input as an exercise in understanding apply
<lexi-lambda>
adamgolding: Since the lambda has a rest argument, and you passed only one argument (which is a list), then `rest` is bound to (list (list 1 2 3)).
<adamgolding>
hrm
<lexi-lambda>
I imagine you either wanted (lambda (rest) ....), ((lambda rest ....) 1 2 3), or (apply (lambda rest ....) (list 1 2 3)).
<lexi-lambda>
Any of those would work.
<lexi-lambda>
When you write (lambda x ....), then `x` is a *list* of all the arguments passed to the function.
<adamgolding>
thanks
<adamgolding>
originally I had (define f (lambda rest(apply + rest))) (define rest (list 1 2 3)) (apply + rest) (f rest)

Did anyone encounter button% not using [font my-font]? my-font is acquired from the-font-list and using it directly with dc<%> works perfectly.

Does anyone have the racket 6.9 mirror? The old one appears invalidated, breaking my docker setup
