Because there's another possible interpretation of the last call: 
"func" is called with the default parameter, 4, and returns a func_ptr; the
function designated by func_ptr is called with one parameter, 5 [no .all is 
necessary on the function access since there is a parameter list], and 
returns an integer (10); and then the P that takes an integer parameter is 
called with the parameter 10.

I wanted to find out whether this was ambiguous because there are two legal
interpretations, or whether there's a language rule I'm missing that makes one
of the two interpretations impossible, or gives precedence to one over the
other.
