In C/C++ there is: __FILE__, __LINE__, __FUNCTION__ ( 
__PRETTY_FUNCTION__ in gcc)

How can this be done in D?

I read in a previous message of something like: build.line or debug.line.

Is this implemented? I tried in dli-0.1.2 but it didn't work.

PS:

A documentation fix is needed in http://digitalmars.com/d/pretod.html

The C Preprocessor Way

	#define X(i)	((i) = (i) / 3)
	

The D Way

	int X(int i) { return i = i / 3; }
	

The compiler optimizer will inline it; no efficiency is lost.

The C version sets the value of "i" while the d version doesn't, "i" is 
passed to the function by value. It should be "inout int i".

Thanks,

The only way to do this in D right now is to run the C preprocessor over the
D source file, and run that result through the D compiler.

Thanks, I'll fix it.
