Bug 12184 – Provide formating options for std.uni.InversionList

Printing an InversionList looks like this: writefln("%s", CodepointSet('a', 'z')); => [97..122) I'd like to request that InversionList support *some* formating options, in particular, 'x' and 'X', and optionally, width. hex would be prefixed with 0x. This would allow printing as: writefln("%04x", CodepointSet('a', 'z')); => [0x0061..0x007b) This would be helpful, as codepoints are often used hex style, and not decimal style.

This is probably easily implementable thanks to techniques like this: http://wiki.dlang.org/Defining_custom_print_format_specifiers
