Estimated hours taken: 4 Branches: main compiler/*.m: Change a bunch of modules to import only one module per line, even from the library. compiler/mlds_to_il.m: compiler/mlds_to_managed.m: Convert these modules to our current coding style. Use state variables where appropriate. Use predmode declarations where possible.
