Question #3:
Related to question #2, if I didn't use hypotheticals, how would I
access the Nth match of a repitition? For instance, in E5, there's an
example that looks like this:
rule file { ^ adonises := hunk* $ }
If I didn't have the

The hypothetical 'variables' we bind to aren't really variables but keys to a hash.
Welcome to Perl 6. Where *no* variable is really a variable, but all are keys to
a hash (which is known as the symbol table) ;-)
Thus they shouldn't have sigils in their

Ok, you're obviously right. But

Coming to think of it, why have a named variable at all? If the
match object gets returned anyhow there is no need for a cleverly
named magical variable ($0, $MATCH, ...).
Probably for the same reason that we have $1, $2, $_, etc.

Question #1:
If \n matches any one of the platform-specific newline character
sequences, does that mean that if I have a string like this[*]:
foo bar baz\rfoo bar baz\nfoo bar bar\r\n
that \n will match in 3 places? How do you tell perl that you only
want \n to match a specific

I think it's to differentiate the different namespaces (scalar, array,
hash) within the match object's hash. Personally, I
