Here's my version of the same, in highly unidiomatic D:

auto nameSet( uint count, uint size ) {
     auto randomWordsRandomLength = map!"a()"(
         repeat({
             return repeat({
                     return cast(char)iota(65,91)[ uniform( 0, 26 ) ];
             });
         })
     );

     return array( take( map!(
         ( randomWord ){
             return array( take( map!"a()"( randomWord ), size ) );
         })( randomWordsRandomLength ), count ) );
}
