Providing integer Default for Number gives compilation error

[klauspost]

Probably a regression caused by fixing integer numbers:

package design

import (
	. "github.com/goadesign/goa/design"
	. "github.com/goadesign/goa/design/apidsl"
)

var _ = Resource("lists", func() {
	Action("get", func() {
		Routing(
			GET(""),
		)
		Params(func() {
			Param("num", Number, func() {
				Default(50)
			})
		})
		Response(NoContent)
	})
}) 

>goagen bootstrap -d goatest/design
exit status 1
goatest\app\contexts.go:44:14: expected operand, found '%!'(MISSING)
goatest\app\contexts.go:47:3: expected ';', found 'if'

[...]
        if len(paramNum) == 0 {
                rctx.Num = %!!(MISSING)f(int=50)
        } else {

%f should maybe be %v. Sending 50.0 as default value works around the issue.

This is actually a different issue, the type is declared as Number and not Integer so the runtime value is a float64 but 50 is an int value. Using 50.0 is the correct thing to do. That being said the data types in the DSL are modeled after JSON - not after the Go type system. So it would probably be good if one could use 50 to specific a Number value. I'll take this as a enhancement request :)
