Thank you!
I fixed, but anyway it works incorrect (it doesn't any changes):

Code: https://rosettacode.org/wiki/Natural_sorting#D
Result: http://pastebin.com/hhSB4Vpn

like this:
["foo1000bar99baz10.txt", "foo1000bar99baz9.txt", 
"foo100bar10baz0.txt", "foo100bar99baz0.txt"]
["foo1000bar99baz10.txt", "foo1000bar99baz9.txt", 
"foo100bar10baz0.txt", "foo100bar99baz0.txt"]

but must be this:
["foo100bar99baz0.txt", "foo100bar10baz0.txt", 
"foo1000bar99baz10.txt", "foo1000bar99baz9.txt"]
["foo100bar10baz0.txt", "foo100bar99baz0.txt", 
"foo1000bar99baz9.txt", "foo1000bar99baz10.txt"]
