<br><font size=2 face="sans-serif">This seems like an obvious statement,
but I am reading the Clean Book and saw this annotation for double:</font>
<br>
<br><font size=2 face="sans-serif"> double :: a -> a |
+ a</font>
<br>
<br><font size=2 face="sans-serif">which reads as "double is a function
which takes an argument of type a and returns and value of type a provided
that a version of + is defined which can handle arguments of type a"</font>
<br>
<br><font size=2 face="sans-serif">But my question is: since (+) is a binary
function, shouldnt that read:</font>
<br>
<br><font size=2 face="sans-serif"> double :: a -> a | +
a a </font>
<br>
