The colons are to make it look more official or something. They are useless 
and hence stupid. The two equals signs for comparison could be argued to be 
redundant, but the colons are absolutely unecessary. I thought they were 
pointless 18 years ago when I learned pascal in highschool and after 20 
years, I still think they are still pointless.
