I looked at "sweeten.sscm" and confirmed that my initial suspicions appear to
be correct.
There are only 3 lines where "(" begins an it-expression
and the n-expression was different than the t-expression:
case x
(quasiquote) '+++CL-QUASIQUOTE-abbreviation+++
(unquote) '+++CL-UNQUOTE-abbreviation+++
(unquote-splicing) '+++CL-UNQUOTE-SPLICING-abbreviation+++
else x
In many cases a "(" starts an it-expression, but the n-expr and t-expr
are the same anyway, so the "ambiguity" doesn't even happen often. E.G.:
cond
(eof-object?(char))
eqv?(char #\;)
... and a number of cases where it was the leaf result like this:
'()
There are similar circumstances where "{" is right after the indent.
Often the t-expression and n-expression are the same thing,
so there's no ambiguity to resolve. In a few cases there *is* an
ambiguity, but I think a t-expression would be a plausible default
as long as you could switch.
