Thanks for the report. This is a new class of error, I suppose is the best
way to put it, introduced with this new implementation. In the previous ad-
hoc implementation, the "parse" would succeed until word expansion, then
fail when the string was run through the parser again to find the closing
`)'.

There's already code in there to handle this case, it just needs different
return values to handle the error differently. There are a couple of ways
to deal with this interactive-only error, so I'll pick one.
