[antlr-interest] Caveat on Using Line-Terminated Comments in ANTLR Grammar Actions

Hi,
I just got an odd diagnostic from the Java compiler when I ran it on the
output of a successful ANTLR invocation. The problem came from this
line of my grammar file:
// $t = fFF.definiteTerm(fFF.makeDetachedConstant($name.text));
ANTLR expanded $name.text with code that included newlines. Naturally,
only the first line of the resulting code was commented, leading to a
syntax error.
