Re^3: Efficient way to verify scalar contents

I'm not sure. I remember [a-z] depending on locale, but it was probably in bash rather than Perl...

$ (LC_ALL=en_US.UTF-8; [[ é =~ [a-z] ]] || echo no)
$ (LC_ALL=C; [[ é =~ [a-z] ]] || echo no)
no
$ perl -Mutf8 -wE 'say "é" =~ /[[:lower:]]/'
1
$ perl -Mutf8 -wE 'say "é" =~ /[a-z]/'

$

Update: Switched from <c> to <pre> and back.

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
