some of them inter-related. (while the phrasing is short, please
don't consider the tone short. =-)
o Undef vs. None vs. null? Only one of these types is mentioned in
the PDD. Need to document the rationale and expected use for each type.
See also: http://rt.perl.org/rt3/Ticket/Display.html?id=33603 :
Undef != Undef.
o Floats - are we sure about the platform default for
stringification? And are we sure we want to limit ourselves? see:
http://rt.perl.org/rt3/Ticket/Display.html?id=31980
o BigNum - note dependence on external library... should this be a
basic type?
o Arrays - Can we have some rationale here to explain the large
number of array types?
o Binary Math Operations - this section needs more explanation.
Perhaps a table of :multi listings for all the basic types.
o What makes a type basic? (static vs. dynamic, core vs. language, etc.)
o There are 71 pmcs in src/pmc types. Only 21 are documented in the
PDD. Are they not basic? (If not, what makes them not basic? where
are they/will they be described?)
o How can I use my own types in place of these types? (e.g. if I want
more precision by default than parrot gives on stringification (like
Tcl does with TclFloat)).
o Morphing is not mentioned. This was a contentious issue the last
time it came up on list.
o Need to mention 'does', which is not the same as:
o the type hierarchy.
