I've redirected the cc's to plt-dev. (please do the same.)

If you're happy with your code only working in drscheme, that's fine.
But I wouldn't be happy with that for the HtDP teaching languages.

In general, the HtDP teaching languages code does not depend on the
drscheme-level preferences and I would prefer to keep it that way.

I'm not sure what Matthias okay'd, but I don't think he would/should
have okay'd that.

The solution seems pretty straightforward, however -- just don't use
string-constants for this. Have two versions of the testing library, a
german one and an english one and just load the right one in the right
teaching language.
