Well, it has been a week now tinkering with Gambit, and my first "bug", found when trying to find a valid example of finding the index of a given character in a string, which I found in the web-server example directory.

The README stipulates the manner of starting the server:

gsi html http web-server 8000

However, the continuation-example calculator does not work unless base64 is also included:

gsi base64 html http web-server 8000

Hooray. This glorious contribution will live in infamy, I am sure.

I think my pains of learning the "Scheme Way" and Gambit would have been much less had I read more of the examples and paid a thorough attention to:

http://www.schemers.org/Documents/Standards/R5RS/HTML/

Instead of playing a guessing game as to which SRFIs are implemented! (string-index from SRFI 13 in particular, for which the web-server has the example I was seeking as "find-char-pos" -- in other words answering my question, "Yes, you do have to write this yourself.").

If nothing else, reading through the http.scm "parse-uri" procedure (and others nearby) makes me wonder if this code was generated or if some human actually did sit down and write all the states...
