If I read this correctly, you're suggesting that I take the text that is
currently coming in on stdin and put it on the command line, right?

Unfortunately, I don't think that's practical here, for two reasons.
First, this particular input is about 13K, and while this is within the OS
limits for command line length, it's long enough to be a pain --- and I
expect to deal with larger inputs at some point.  Second, the input is an
sexpr representation of a Java class definition, and there are lots of
string literals inside it, so I'd have to escape double quotes and
backslashes throughout.

I'll probably just bite the bullet and have the script take the input
filename as a command line argument, with the standard unix shorthand of -
for stdin so I can continue to use it in a pipeline from the shell.

Thanks,
