I checked in the fix.

Of course you also want to consider why you're doing 'eval'
so many times - unless it is just for testing.  You'd want
to avoid compiling the same code many times, since that
may be expensive.  One alternative is to eval an expression that
evaluates to a procedure, which you can save and call many  times.

If you're writing web server code, consider using the
"KawaAutoHandler" mechanism, which automatically uses
compiles and re-uses a "script":

If this doesn't work right, I want to fix it!
