On #perl6 Larry said that STD is a part of the specification for perl6.
Would it be possible to include a link to STD.pm in the list of official
documentation?
There are things in STD that are not in the specifications, eg., default
values for optional parameters should come after traits

I was looking through STD.pm at the parsing of metaops. I was
exploring to see if the legal metaops for a given operator could be

in the pugs repository:
$ cd src/perl6
$ make
$ ./tryfile $filename
That assumes a perl 5.10 in /usr/local/bin/perl
HTH,
Does that mean there is a tool I can use to apply STD.pm to syntax-check
my examples or ask questions of it? Can you point to that?

I don't understand your point. Are you thinking of .callwith or

No, I think of foo not as a Code object but as a class that
does Code. Invoking foo mea

No, but that is the same as with other sigiled terms.
You can also do funny things like

The spec doesn't define namespaces to be protected in any
way. The above is naturally limited to the compile run,

should work. The type system is a runtime overlay to
the value system. This is reflected in the source by
putting types and values into different syntactic slots.
You cannot mix these!

I think my declares value variables which means you need
a sigil:
my ::RunTimeType $ := GetType;
and of course you capture the runtime type of the
return value of GetType. If you write that as
m
sub GetType (-->Type) { ... }
my ::RunTimeType := GetType;
This is clearly permitted by the prose, that " ::x may be bound to any object
that does the Abstraction role, such as a typename, package, module, class,
role, grammar, or any other protoobject with .HOW hooks."

I'm trying to fathom STD.pm.
Maybe someone can help me trace through this one?
How is
$obj!privA = 1;
parsed?
Reading expect_term, it trys , then sees the "$" and commits
to the decision, reads "obj" as a , then checks for a ".", but

Something is choking
OK, you got me. What is the "¢" used for? For example, .
I only see that character as used in this manner (a variable name?), never
defined (e.g. as a variable or parameter) anywhere.
