Hi All,

Is $YugeBuf (up to 100 MB) a copy of just the structure?
I don't want the time time of a copy.
Many thanks,

WHERE is pretty sweet command!
$ p6 'sub a (Buf $b) { say $b.WHERE.base(0x10) }; my $c =
Buf.new(1,2,3); say $c.WHERE.base(0x10); a($c);'

In
{l for l in L}
The reason it is in `{}` is to create a Set from iterating over `L`.

So in Python:
[ l for l in L ]
Hi all,
I wonder what would be the Perl notation for 'set-builders', as exposed
in this wikipedia article:
https://en.wikipedia.org/wiki/Set-builder_notation#Parallels_in_programming_languages
This is the Python notation:
Example 1: {l for l in L}
Example 2: {(k, x) for k in K for x in X
