Hi Eugene
You don't need to supply all the arguments to a constructor at once:
makeWithOne :: String - (String - String - Object)
makeWithOne s1 = \s2 s3 - Object s1 s2 s3
-- or even:
-- makeWithOne s1 = Object s1
This builds a higher-order function that can be applied later to two
Strings to

Hi Eugene
Is something like this close to what you want:
For example this builds an object with ordered strings...
makeOrdered :: String - String - String - Object
makeOrdered a b c = let (s,t,u) = sort3 (a,b,c) in Object s t u
Alternatively you could build the with the Strings as they appear

Hi Steffen
True - but it does include a partial pattern (that will always match
in this case, of course).

In fact it doesn't make any difference, so both these names are equal :)

Not really. First of all, there're many properties, not 3. So it may end up
with plenty of support (boilerplate) code.
Also, names of these parameters are not sortable. Of

Wow! Thank you, that's it :)
