The colon is a bit overused (ranges, ternary, quoting), but this would be pretty clear with parentheses and spacing, i.e. ex.head == :(.) and ex.head == :(call). Now you can see it's a comparison against the symbols '.' and 'call'. Kind of like saying C has too many weird character combinations because there's a "--> operator".

Indeed there are no special operators, :. and ==: etc. They are just :, . and ==

And macro definition code looks quite different from 'regular' code since it works so much with expressions and symbols.
