Thank you, thank you! This bit of documentation has been sorely needed for a long time. Many people come to Guile from the "C side" with poor or nonexistant Scheme experience. Usually to add Guile to some C application, which of course throws out the REPL and it's backtracing and error reporting capabilities. So then when errors happen you have no idea where or how. Making a C program extended by Guile spit out a proper backtrace is a twisty maze of handlers and catchers, and some of them need to be lazy. (Lazy? Why would I want a *lazy* handler, I want a hard-working, full-featured kind of handler, not some wimpy light weight *lazy* handler!)
My point is that getting good backtraces from C is non-obvious and a huge hindrance to people just learning how to use Guile and Scheme. But that's over now. Thanks again Neil.
