digitalmars.D - std.format %p and TypeInfo_P

I'm getting tired of typing %#010x and casting so I can format pointers and having this FormatSpecification not be portable to 64-bit pointers. I looked at std.format.doFormat and it seems most of what's needed for a 'p' FormatChar is there (everything except for switching for 'p' at the Lnumber: label, it seems) ('p' is even already checked for on line 472 of format.d but not used otherwise). But the TypeInfo of pointer types isn't using TypeInfo_P, just the base TypeInfo, and doFormat needs the TypeInfo's classinfo.name.length >= 10 so it can deduce the type from the 10th char, otherwise it fails; so it seems TypeInfo_P for pointer types is also needed before formatting them can work. Does anyone else feel the need for std.format to do pointers?

I'm sick of typing "%0.8X" for every address I want to look at. It would be nice if I could do something like this instead:int foo; format("%p",&foo);output:(int*)0x12345678- EricAnderton at yahoo
