Walter Bright:
Any proposal for column number tracking must take these issues into account.Also note that g++ and clang are hardly noted for their fast compile speeds. Also note that g++'s compile speed has dropped significantly lately - I don't know why, but it also added column number support recently (!).
If someone writes a front-end patch to show column numbers we'll have to benchmark it and decide how much complex/buggy it is and how much extra memory/time it asks for.
