Here you go:

#
# template insertChar(char[] chr, char[] str)
# {
#     static if( str.length == 0 )
#         const char[] insertChar = chr;
#     else static if( chr[0] <= str[0] )
#         const char[] insertChar = chr ~ str;
#     else
#         const char[] insertChar = str[0..1] ~ insertChar!(chr, #
str[1..$]);
# }
#
# template sort(char[] str)
# {
#     static if( str.length == 0 )
#         const char[] sort = "";
#     else
#         const char[] sort = insertChar!(str[0..1], sort!(str[1..$]));
# }
#
# template slice(char[] str)
# {
#     const char[] slice = str[1..$-1];
# }
#
# pragma(msg, `sort!("bsakdjfyiu4r") == ` ~ sort!("bsakdjfyiu4r"));
#
# void
# main()
# {
# }
#

Tested it just then :)
