Estimated hours taken: 5 Branches: main Fix a bug reported by Doug Auclair. library/ops.m: Change the Mercury arg priority to 999. It was previously set to 1201, which allowed arguments and list elements to be parsed the way we intended. However, this had the unintended side effect that valid terms were written out using incorrect syntax. library/parser.m: Place the workaround here, where arguments and list elements are read. Note that this is still technically buggy, because we effectively allow syntax which should be illegal according to the operator precedence table. But the proper fix for this involves moving to a BNF style parser, so that is left for later work. tests/hard_coded/Mmakefile: Run the term_io_test case twice, checking it against the expected output each time. The first time it is run with the supplied input file. The second time it is run with the expected output as input -- this ensures that terms are read in the same way that they are written out. tests/hard_coded/term_io_test.m: Read input from stdin rather than a fixed file. tests/hard_coded/term_io_test.inp: Add additional input terms. tests/hard_coded/term_io_test.exp: tests/invalid/*.err_exp: Update the expected output for this and other test cases.
