#![feature(generic_const_exprs)]
fn foo<const L: usize>(_a: [u8; L], _b: [u8; L]) -> [u8; L + 1] {
[0_u8; L + 1]
}
fn main() {
let baz = [[0_u8; 1]; 8];
let _: [u8; 4] = foo(foo(foo(baz[0], baz[1]), foo(baz[2], baz[3])), foo(foo(baz[4], baz[5]), foo(baz[6], baz[7])));
//let _: [u8; 3] = foo(foo(baz[0], baz[1]), foo(baz[2], baz[3]));
}As shown in the commented line, two levels of nesting compiles, three does not.
