You have the right idea. Notice 'MappingPackageInternalHacks1 D1'
above.

In this example you want D1 to be Float.

So what you need is an explicit "package call" like this:


(1) -> iter ((x:Float):Float +-> cos x, 10,
1.0)$MappingPackageInternalHacks1(Float)

   (1)  0.7442373549 0055686343
   Type: Float

Or if you wish, you can explicitly "expose" this package:

(2) -> )expose MappingPackageInternalHacks1
   MappingPackageInternalHacks1 is now explicitly exposed in frame
    initial

(2) -> iter ((x:Float):Float +-> cos x, 10, 1.0)

   (2)  0.7442373549 0055686343
   Type: Float
