auto-reduced (treereduce-rust):
pub enum Sexpr<'a> {
Ident(&'a mut S),
}
fn map<'a, F: FnOnce(&Foo<'a>) -> T>(f: F) {}
fn main() {
map(Sexpr::Ident);
}
original:
pub enum Sexpr<'a> {
Ident(&'a mut S),
}
fn map<'a, F: FnOnce(&Foo<'a>) -> T>(f: F) {}
fn main() {
map(Sexpr::Ident);
//~^ ERROR type mismatch in function arguments
