generate outputting invalid go code

[MendyBerger]

wit-bindgen-go generate sometimes outputs invalid go code.
Seems to be happening with variants.

I have the following wit

package webidl:my-package;

world my-world {
    import my-interface: interface {
        variant my-variant {
            foo(my-resource),
        }
        resource my-resource {
            my-method: func(param: my-variant);
        }
    }
}

go run go.bytecodealliance.org/cmd/wit-bindgen-go generate -o internal/ wit

Outputs:
Error formatting file: error in abi.go: 13:34: expected type, found ')'

The actual api.go looks like:

// Code generated by wit-bindgen-go. DO NOT EDIT.

package myinterface

import (
	"go.bytecodealliance.org/cm"
)

func lower_MyVariant(v MyVariant) (f0 uint32, f1 uint32) {
f0 = (uint32)(v.Tag())
switch f0 {
case 0: // foo
v1 := cm.Reinterpret[uint32](*v.())
f1 = (uint32)(v1)
}
return
}

My understanding is the *v.() is the problem (I'm new to go)

Something weird I noticed: changing the namespace name from webidl to my-webidl resolves the problem with this specific wit, but not with other wit 🤷

Thanks, we'll take a look!
