:| :	print "found x-twoslash-dollar-pat\n";
:| :}

:| This time you didn't escape the $, so it's anchoring
:| at the end of the line.  Shouldn't match.

:Uh, wouldn't the $$ expand to the process ID of Perl, since the backslash is
:escaped?

Yup, perl seems to scan left to right here, so would pick up $$ before $pat.
