stl and yaws

Without support for call-with-current-continuation I see only two
approaches:

1. syntax transformation (may be I try it somewhere).
2. Continuation style programming as Distel does.

Now I use the second one. Every function must return

{ok, Result, ContFun, ContArgs} | {ok, Result, die}
