s/\b__(\w+)__\b/\U$1/;

Good point! I’d forgotten about these (if I ever knew them¹) — except for \Q, which I often have to use. For the record, they’re documented here:

“Escape sequences” in perlre#Regular-Expressions
perlop#Quote-and-Quote-like-Operators

abcDEFghijk

Good to know, thanks!

Update: ¹I must have read about them any number of times. But unfortunately it seems that reading about ≠ knowing, unless it’s combined with using. ;-)
