During reading Scala documentation i confused with some functions signature: <pre class="prettyprint"><code>def corresponds[B](that: GenSeq[B])(p: (T, B) ⇒ Boolean): Boolean </code></pre> So, what does exactly this mean? <pre class="prettyprint"><code>(p: (T, B) ⇒ Boolean) </code></pre>

It means <code>p</code> is a function taking two arguments of type <code>T</code> and <code>B</code> and returning <code>Boolean</code>.

Scala function signature: What does (p: (T, B) ⇒ Boolean) mean?

During reading Scala documentation i confused with some functions signature:

def corresponds[B](that: GenSeq[B])(p: (T, B) ⇒ Boolean): Boolean

So, what does exactly this mean?
