Dunno, but I have found that Americans and non-Americans alike have trouble making connections without the conclusion spelled out for them. Simple programming example; consider:

   my %hash = ( foo => 42, bar => 123 ); # create a map
   Class->new               # instantiate class
   Class->new( foo => 42 )  # instantiate class, setting foo = 42
   Class->new( bar => 123 ) # instantiate class, setting bar = 123

With this in mind, how would you instantiate Class, setting foo to 42 and bar to 123? Many people are stumped, and wouldn't even think to try:

    Class->new( foo => 42, bar => 123 )

This confuses me. So I am now careful to spell out conclusions after showing the reader what facts I used to reach them.
