Hello! I got the following at
"http://perldoc.perl.org/perlretut.html#Non-capturing-groupings" regexp tutorial, in the Non-capturing groupings section:

$x = '12aba34ba5';
@num = split /(a|b)+/, $x; # @num = ('12','a','34','b','5')
@num = split /(?:a|b)+/, $x; # @num = ('12','34','5')

Well...
I can't quite work my way around the first "split" operation.
Also, it appears that @num = ('12', 'a', '34', 'a', '5'), i.e., 'a' as the 4th element, and not 'b', as specified.
I'd really appreciate it, if someone could perhaps explain how the above 'split' operation actually works.
Thank you!
