Actually, if you change it to .*| -- this will work as you
expect. It's a bug that your version doesn't work, of course. It does
seem to involve tangentially, but it is unrelated to underscore.

This issue surfaces because of the token TOP line. If instead of
| only ruport was used the testcase works for both cases. So it
is quite
possible that the bug is elsewhere but shows up as a difference between
alpha and alnum.

This is in conflict with the documentation at
https://docs.perl6.org/language/regexes which states
Alphabetic characters including _
And
\w. plus
In my example.
'_' matches the alpha regex.
As per specifications, Everything that matches alpha should match alnum.
Which in the given example

Golfs to just the top grammar, which is the only one that returns Nil.
grammar Alnum1 {
token TOP {|.*}
}
grammar AlnumReversed {
token TOP {.*|}
}
grammar Alpha1 {
token TOP {|.*}
}
my $rx = rx/^ [|.*] $/;
my $str="n~";
.say for "=== ==",
Alnum1.parse($str),
"

The issue doesn't seem to be the underscore, because I get the same result even
when converting the underscore into a letter ('b'):
$ cat gentb.p6
grammar G0 {
token TOP {|.*}
regex rport { }
rule ruport { }
#token type {+}
token type {+}
}
grammar G1 {

Are you sure about that? Underscore has been part of the specs (synopses)
for for at least 10 years, probably longer.

"_" is not an alphabetic character. It's allowed in "alnum" because that is
by intent what is \w in other regex implementations, which includes "_".

In the attached code, the only difference between the Grammars G0 and G1
is the defination
