For uppercasing, of course, there is also the builtin \U. 
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:

    19:11 >perl -wE "my $s = qq[abc\Udef\Eghijk]; say $s;"
abcDEFghijk

19:13 >

    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. ;-)
