Expand description
Returns whether this method is expected to have a body we can analyze.
Specifically this returns true
if function
refers to an associated item
of a trait which has no default value.
Note: While you are supposed to call this whit a function
that refers to a
function, it will not crash if it refers to a type or constant instead.
