Re^3: Using /m when $ is followed by punctuation

[ikegami]

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.
