Shouldn't that be fixed? |

@ChrisDenton it probably should, but I don't have resources to do that |

Sure, I was thinking more of making an issue or something. |

I've spent 1.5 hours debugging this while trying to compile #112400, if we use
compile_error!, we should not just forward user input to it, but issue a reasonable error message.The better solution would be to use a lint like
clippy::print_stdout, but since we don't have clippy in CI, let's at least make the macro error better.Also note that some functions called here actually do use
println(see for exampleprint_type_sizesfunction).
