Slips are not handled correctly

$ perl6 -e 'use Data::Dump::Tree; ddt (1,2,3).Slip'

Implemented as a special case by wrapping Slips in Data::Dump::Tree::Type::SlipWrapper, Another attempt, handling the Slip as an object as long as possible before passing it in a list, had too large an impact on the code base.

FWIW, Slips need special handling throughout the Rakudo code base to give them their magical properties.

It made me crazy, once I got it to display properly I found it that the changes broke everything else, I didn't have enough tests to find the errors, running the examples in the distribution, which unfortunately don't all have corresponding tests, showed that even making a diff between two data structures was broken (my favorite part of DDT).

10 lines to handle Slip, and everything works like before, not sure if a hack like that shouldn't be called the best solution.

Thank you for reporting it, maybe ;), I am not sure how many people need to render Slips.

I needed it because I have a large array of arrays and hashes and wanted a cheap way of making it object oriented. So I have a role that you just like the keys, and it will automatically create methods for that accessing that key in the hash (very much like standard Perl 5 objects). The problem was with the arrays, because they got itemized. This meant you couldn't do for $obj.array", because it wouldn't iterate. But it *does* if you bind the key to a Slip` :-) Which is a bit of a hack, but it works really nicely and smoothly :-)

An example of the data structure, what you wanted to do with it and how the Slips where used would make a nice technical article for many I think.

The thought has crossed my mind

If you write an article, I need to see more of P6 usage, and do dumps with DDT, let me know if you want some help with filters if the wrap_highlight example is not enough, or a review.

for presentation, and quite often for oneself too, :flat(0) can give a nicer/more usable display, even if it is slooooow.
