Hello all,
I hope everyone is having a good start to the new year.
As Audrey's posts have mentioned, we are starting to work on
container and boxed types in the PIL^N/PIL2 runcore. Over the
holidays I went through the most recent Synopsis and attempted to
compile a list of what I think are the core Perl 6 "types" based on
what was mentioned in the various Synopsis.
I say "types" because I want not to get into a discussion on type
theory/lattices/etc. or anything of the sort right now. I want only
to try to grok the hierarchy of types so that I can begin to build
the container and boxed types in PIL^N.
Now the closest thing to a full list I found was in S06, but it
seemed to leave out some things mentioned in the other (possibly out
of date) Synopsis, so I built the table below.
In addition to just listing them, I also attempted to (loosly)
structure them into a hierarchy to illustrate the (sub|super)-type
relationships. The table is split into 3 columns, the first the type
(tab depth determining place in the heirarchy), the second is the
Synopsis it was mentioned in (a blank value in this column means it
was in the S06 list), and lastly a description of the type (if it's
meaning not obvious that is).
I am sure I am probably missing a few, have mistakenly put others in
the wrong place in the heirarchy, and/or I may even be completely and
totally in the wrong in every way. But I figured it was a start, and
I would see what others had to say.
Thanks,
Stevan
