Implement :repeat()

[Snaipe]

the repeat method would allow one to repeat a field N times (or until a passed callback returns true)

Usage:

array = wssdl.packet {
    data_len : u32();
    data_array : u32():repeat(data_len);
}

-- Describe null-terminated strings
stringz = wssdl.packet {
    str : u8():repeat(function (e) return e != 0 end);
}

Any progress on this?

It's being worked on, but I have limited time these weeks. The main problem for the feature is that, while I can repeat the parsing process of one primitive field, this becomes much more complicated when the field is a compound type, as wssdl still have to be able to process repeat-until-constant-sequence definitions.

So any progress now? Feel interesting about the project.
