Hello,
I'm wondering how to write anonymous value literals of some Perl 6 basic types,
and I didn't see mention of this in synopsis 2.
Now, with some basic types, I know how to do it, examples:
Bool # Bool::True
Int # 42 or 0x17 or :12<AB9>
Rat|Num # 18.2 or :8<53.07> or 4/3
Str # 'Hello world'
Pair # :key<val> or key=>val
Range # 1..10
Junction # 'a'|'b'|'c' or 'e'&'f' or any(5,20) or none(60,87)
Seq # (5,6,7)
Array # [8,9,10]
Hash # { :a<b>, :c<d> } or { a => 'b', c => 'd' }
Correct me if I'm wrong with the above.
But some significant ones I don't know and really want to know:
Bit
Blob
Set
Bag
Mapping
How does one write anonymous value literals of those types? And I mean
directly, not by writing a literal of some other type and using a conversion
function to derive the above?
The above is my main question, but also I wonder about how to make an anonymous
literal of a KeyHash|KeySet|KeyBag. And also how does one specify a Rat vs a
Num or what does "18.2" or "4/3" actually get you? And also is there such a
thing as a Buf literal and if so how do you write one?
Thank you. -- Darren Duncan
