[BUG] LLVM ERROR: Failed to infer result type(s).

[andrew-suprun]

Bug description

The compiler failed to compile the script that, probably, it should.

Steps to reproduce

The script:

from collections import Optional


@value
struct Node:
    var child: Optional[Node]


fn main():
    _ = Optional(Node(None)).value()

The stack trace:

/Users/andrewsuprun/dev/mojo/hello-world/hello.mojo:5:8: error: expected struct operand
struct Node:
       ^
LLVM ERROR: Failed to infer result type(s).
