[pd-giz-dave]

Describe the bug

Attempt to compile this:

module main
import json
@[heap]
pub struct Logger {
}
struct SaveParams[T] {
	object &T
}
pub fn (mut l Logger) save[T](p SaveParams[T]) {
	json.encode(p.object)
}
struct Object {
	s1 string = 'a string'
}
fn main() {
	mut logger := &Logger{}
	logger.save(object: &Object{}) //to_save)
	println('\\o//')
}

It results in:
