Parse errors

Parse errors can be particularly hard to locate and fix. A typical parse error looks like the following:

? (libload "main")
*** read : end of file
Debug toplevel [y/N] ?

You can narrow the error down to the file that was misparsed by answering 'y' and printing out fname:

? (libload "main")
*** read : end of file
Debug toplevel [y/N] ?y
