Details:

Given this comment in kawa/lang/SyntaxTemplate.java:

            /* FIXME cycles are OK if data are literal. */
            tr.syntaxError("self-referential (cyclic) syntax template");

Would you like me to create a minimal test case?  I do not want to waste my
time, since you seem to know about a bug that causes this error.  My program
dies with this error under Kawa but works under Chibi.  Looking at my syntax
templates, I do not see how they can be cyclic, but they are very complex, so
I am unsure.  Perhaps there is some --debug option to print each template as
it is applied...
