To make it easier on people writing these tests, it might be nice for
this to be less noisy by getting rid of "@" and "\". To get rid of
"\", the test program could grab its script commands from stdin (one
instruction per line) rather than from argv[]. For instance:

    test-json-writer >actual <<-\EOF &&
        object
            object-string a abc
            ...
        end
    EOF

Not a big deal, and certainly not worth a re-roll.
