There's a significant difference between data constructors and ordinary
functions - you can't use pattern-matching to match an ordinary function.
In effect, data constructors are used not just to build values but also to
take them apart.

Syntactically speaking, data constructors must begin with a capital
letter, variables and function definitions with a lower case letter.
