Heads-up: code was correct in my last post, but the output is as follows
(Rakudo v2021.06):
~$ raku -e '++(my %digraphs){$_} for slurp.lc.match(:global, :exhaustive,

Hi Marc (and Bruce)!
I'm adapting a "word frequency" answer posted by Sean McAfee on this list.
The key seems to be adding the `:exhaustive` adverb to the `match` call.
AFAIK comb will not accept this adverb, so `match will have to do for now:

That makes some reasonable sense. I guess "is required" and native attributes

Hi,
The following fairly simple code works well:
class A {
has num $!a is required is built;
};
dd A.new(a => 1e0);
producing "A.new(a => 1e0)".
However, if we make a slight change:
class A {
has num $!a is required is built;
};
dd A.new(a => 0e0);

With the change from Perl 6 to Raku, there were a number of naming
changes, particularly of file formats, eg pl6 -> raku, pm6 -> rakumod.
One of the changes was `.pod6` to `.rakudoc` for files that are
primarily documentation files.
However, we continue to refer to POD6 (also known as Pod6)

No such method 'base' for invocant of type 'Str'. Did you mean any of

Hi Todd,
It's great that you've delved into the "encode" docs.
However to answer your question, I think you want to look at the
"encoding" routine page:
https://docs.raku.org/routine/encoding#class_IO::Handle
Here's the list on that page:
utf8
utf16
utf16le
utf16be
utf8-c8
iso-8859-1
Hi All,

multi method encode(Str:D $encoding = 'utf8', :$replacement, Bool()
:$translate-nl = False, :$strict)
shows "ascii" and "utf8" as possible values for
"$encoding".
I tool a guess and found out "utf16".
Where are the rest of the values

No such method 'base' for invocant of type 'Str'. Did you mean any of
these: 'Bag', 'Date', 'Hash', 'are', 'asec', 'hash', 'take'?
Typo.
Should have been:
append to Buf question
And in my Keeper, I keep typing "bugger" instead
of "buffer". Can't win.

Did not realize I could use buf new like that. Thank you!

I am updating my Keeper on buffers. I have four of them
that are a mess and I an going to consolidate them into
a single .ODT (open document text) file with an index.

Stringification of a Buf is not done with 'Str'. The 'decode' method
should be used

Clever!
I had missed checking "is-prime" straight away! Checked some large
primes, and my function hung badly. Thank you!
Is grep running on all "2 ..^ $n/2" values, and then picking the first,
or is that somehow lazily evaluated? I assume the former, or you'd have
no need to halve $n. But
Frederick P. Brooks, from the additional material in the 1995
edition of "The Mythical Man-Month" (1975):
"Much more is known today about software engineering than
was known in 1975. Which of the assertions in the original
1975 edition have been supported by data and experience?
Here's my new go to prime-factors function :
sub prime-factors( Int $n is copy where * > 1 ) {
gather {
while ( $n > 1 ) {
if ( $n.is-prime ) {
take $n;
last;
}
my $f = (2..^$n/2).grep($n %% *).first(*.is-prime);
This is because if there isn't an explicit return the last statement
evaluated is the implied return value.
So the last call (which returns Nil) was your implicit return.
Generally I try and avoid an implicit return if a function has more than a
couple of lines.
