Formatting more types

Description

tango.text.layout.Convert fails to format some rather important types.

1) Arrays. 2) AAs. 3) Structs.

The last one brings us tangentially to another Tango design decision. The compiler inserts helper code for the toString method of structs in TypeInfo?_Struct.xtoString. If the struct defines a toString method, it's non-null; if not, you can just output {unhandled argument type}. Of course, the Tango Way (TM) is toUtf8, but that's been met with considerable opposition.. that's not what this ticket's about though.

Lastly, it formats pointers as decimal numbers. Could they be hex instead, possibly defaulting to padded to 8 chars wide on 32-bit and 16 chars on 64-bit?

yeah, arrays will be supported. Structs are a known pain, and we hope to rectify that somehow via the conference. Can you format your pointers using {:x8}

Another one: there's no way to format an integer as a char, like the %c specifier for printf.

This is annoying when I want to take advantage of positional specifiers: Stdout.formatln("{} {0:x} {}", integer, cast(char)integer) currently requires the cast to char. I'd prefer Stdout.formatln("{} {0:x} {0:c}", integer) or equivalent.

Array support was included recently by keinfarbton, and Tango now uses toString. Sorry you had to wait so long for this
