  • s/([\.\(\)\^\$\@\[\]\*\?\+\{\}\#\\])/\\$1/g;

    Is there a difference from $_ = quotemeta $_;?

    • I think quotemeta is a bit more verbose. Like it seems to quote everything that's not \w.
      • Ah, yes. Actually I just remembered that quotemeta is in fact problematic for this purpose because backslashes are not treated the same in regex quoting context vs double-quote quoting context. Which annoyed me when I was trying to interpolate user data in a the s/// pattern in a string to be evaled.
