Three years is a long time in Internet time.  And Stalin is manifestly
a dead end: it does what it does, but it's a nightmare to maintain for
anyone but the author, especially given that the internal documentation
consists of "LaHaShem HaAretz U'Mloah" at the beginning and "Tam V'Nishlam
Shevah L'El Borei Olam" at the end of each source file. :-)

Still, someone could provide Stalin with a preprocessor that did
syntax-rules and added support for (probably) everything in R5RS except
dynamic-wind.  (Multiple values would have to cheat, as is the case in
chibi-scheme, where values returns a list of values with a unique object
in the car, and call-with-values merely checks for this.)
