One of these years I'm going to make a Finnish programming language that enforces the correct case in arguments. And I don't mean silly arguments like camelCase vs kebab-case, I mean grammar.

Some examples to illustrate:

  tiedosto on "foo.txt" avattuna
  tulostin on PRN1
  kirjoita(tiedostoon, "a")
  kirjoita(tulostimelle, "b")
