Line number logging with __LINE__ doesn't work

[c42f]

As pointed out by @quinnj, @__LINE__ doesn't do what a C programmer naively expects :-/

This could come from a backtrace instead, it just seems a bit excessive to invoke one to get something that could/should be inlined at the call site.

For reference, I copped out by just requiring the line number as an input to the macro; see here

Ah, that's a pity! Thanks for the xref :-)

@ihnorton has a scary looking hack that gives better results here
JuliaLang/julia#8066 (comment)

but it still doesn't do quite the right thing.

Perhaps there's just no solution to this at this stage.

This is solved in 0.7 thanks to JuliaLang/julia#21746

There is no, and will be no solution to this before 0.7 is released, by the looks of things.
