          Issue ID: 15613
           Summary: Parameter type mismatch error message are not very
                    helpful
           Product: D
           Version: D2
          Hardware: All
                OS: All

Example of such an error:

--------------------

source\mymodule.d(244): Error: function distance.Distance.nextBuffer
(const(float)* inputLeft, const(float)* inputRight, float distanceDB, float*
outL, float* outR, int frames) is not callable using argument types
(const(float*), const(float*), float, float[], float[], int)

--------------------


One must mentally parse the entire message to find that parameter 3 and 4
should be float[] but are float*. It gets the worse the longer the function
prototype is.

It would be great if the compiler can do it and give the parameter index that
mismatches.
