Drop the useless \$.
```/ \$ \n /xm
is the same as just
```/ \n /xm

Thanks, I see that now. Do you know of an answer to the general question: how to get perl to parse \$ followed by by an escape sequence as \$ \whatever rather than \$\ whatever?

I don't think you'd ever need to do that, but I can think of a couple of solutions:

• (?x: \$ )
• (?=\n|\z) (if /m is in effect)
• (?=\n?\z) (if /m isn't in effect)
• (?![^\n]) (if /m isn't in effect)
Thanks, ikegami. I had remembered that there seemed to be no need for an interior \$ followed by an escape, but I failed to think outside the box I had constructed for myself in the original question.
