What I would love to have is an equivalent to C predefined macros:
__LINE__ - expands to the line number of the source file where it's encountered__FILE__ - expands to the source file name__VERSION__ - expands to the version of the compiler used to compile the source
I do most of my debugging with logs and while it's easy to find the position in the source file with the unique log message, sometimes I write "logging function" which dumps a data structure, or state or something like that. And I would like to have a simple way to correlate the log output for such function with the position it was called from.
@paf31 suggested to exploit failed pattern match messages, but while it's good for logging errors in case of catastrophic failure, I believe it's too expensive for casual high volume debug logging.
