[racket] DrRacket WM_CLASS on X

For DrRacket running with the X Window System, would it be possible to 
set the windows' "WM_CLASS" to "DrRacket"?

"xprop" says that there is no "WM_CLASS":

[...]
WM_CLASS(STRING) = "<unknown>", "<unknown>"
WM_ICON_NAME(STRING) = "Untitled - DrRacket"
[...]
WM_NAME(STRING) = "Untitled - DrRacket"
[...]

Setting "WM_CLASS" would help out fancy features in X window managers 
like XMonad.
