I'm certain that this was recently answered on this group, but I can't
seem to find it. For instance, if I am using #lang racket/base, how would I
figure out that I need "racket/contract"? (my current solution is "grep" or
Google ... but I was hoping for a more elegant solution).
#lang racket/base
Yes - WeScheme is awesome - and so is

Suggestion: upvote racket on repl.it so you can run it from everywhere:
https://repl.it/language-requests/p/racket
(I know it is unlikely to be as good as the full DrRacket or racket-mode
experience)

My guess is that the GUI system under 2htdp/image remembered the color
was drawn with an alpha value of 100 but there isn't enough resolution
to determine the difference between 50 and 48 when you are at 101/256
(or whatever the alpha as a percentage really would be ...).

There is a TOC at the beginning of the post, but I'd add a link to the next
post at the end. Something like:
"Next article in the series: From HtDP to Racket. Racket (2): only-in,
rackunit, test submodules"
I'd put one at the very end and other just before the code.
