Because we can. Or rather, we should can, because <br>

5 :: Num t => t<br>

• Cannot apply expression of type ‘t0’<br>

• In the expression: 5 @Double<br>

is confusing and inconsistent with the user’s expectation after<br>
learning about when they can use ExplicitTypeApplications (unless one<br>
knows about the syntactic sugar involved.)<br>

thanks, fixed.<br>
