`<<>>` is the same as `qqww<<>>`
Which is short for `Q :qq :ww <<>>`
the `:qq` is short for `:double`, that is it turns on double quote behaviour
`:double` is short for `:scalar :array :hash :fun
Perl 6 (Timo),
In terms of new() uses… I’ve seen a clever use of new() that goes beyond
turning ‘positionals’ into ‘named’ in

Thanks for that. As a worka-around Rakudo seems to do a better job, if I
give it a helping hand viz a TWEAK method:

}
class MyStruct2 is repr('CStruct') {

has int8 $.f

Timo,
Oops. You're right. (I was unconditionally sending an argument in my test
that zeroed it out the attribute that I was watching -- doh!) Now I can
confirm that TWEAK is the logical place to further initialize attributes.
I now see the light!
Thanks,

The main difference between BUILD and TWEAK is that BUILD will replace
all default and requiredness handling, while TWEAK keeps it intact.
TWEAK gets run after these aspects had their turn, so if you have an "is
required" attribute that doesn't get a value passed, the BUILDALL
process will throw th

IIUC - close, it like qqw:

It's actually synonymous w/ qqww but depending upon your use of quotes w/i

No need for .Num, just write it as 1e0
