The default format prints a lot of details like filename, line number, and the source code on that line. A particular case where the warn message is written on the next line like -
warn(
   "Message here")
Will only print warn( as the source code and not the entire block.
My concern is, can this formatting be less detailed by default. Or, can this format be freely changed in a project A without worrying about affecting the global usage in any other project B that imports it.
Or at the very least, can this be made to print the entire block of code and not just the one line, because that makes it very confusing for the user.
