[racket] examples of hooking a #lang into DrRacket?

Pollen source files run fine in DrRacket. But the `#lang pollen` line shows up as red (though no error is reported in the bottom of the window) and no toolbar buttons are available. So something is not quite right.

I gather that this has something to do with telling DrRacket about language-specific capabilities. [1]

However, many of the custom #langs in Racket use the standard #lang s-exp syntax/module-reader, which seems to eliminate these problems from the start.

Q: To supplement the documentation, are there particular #langs that show examples of this kind of configuration file?
