Question, I've been using Ruby for a while now and I have a perlism I
kind of miss.

Given

$str = "foo123";

my ($foo,$bar) = $str =~ /(\w+)(\d+)/;

# now we have
$foo; #=> "foo"
$bar; #=> "123"

I know that I can do this in Ruby in TWO lines, but I want to do it in
ONE line. Anyone have any ideas?

Something like:

foo, bar = "foo123".match(/(\w+)(\d+)/).captures

p foo
p bar

pth

Better: foo, bar = "foo123".match(/(\D+)(\d+)/).captures

str = "foo123"

foo, bar = str.split( /^(\D*)/ )[1..-1]

foo, bar = str.scan( /\D+|\d+/ )
