haskell中函数只有一个参数吗？

izhier

programming in haskell

The difference between normal functions and constructor functions is that the
latter have no defining equations, and exist solely for the purpose of building
pieces of data.
Not surprisingly, data declarations themselves can also be parameterised.

问一下
以上红色的部分怎么翻译呢 ？
都碰到好几回了

难道是可被作为函数参数或可作为模式匹配 ？
