But for a IDE that has to parse the error messages to show something graphically the error message with the "^" can be better.
I think column number would be a lot easier for an IDE to parse than a "^".
Regarding the excessive amount of lines of error messages shown on the command line when you use the "^", with DMD I usually only read the first error message or the few first ones, ignoring the successive error messages, because the successive ones are usually useless. With GCC I sometimes use a compilation flag (-Wfatal-errors) that when present makes the compiler show only the first of few first error messages. Bye, bearophile
