What did you do?
./v -g -o vdbg cmd/v && ./vdbg blog.v

module main

fn main() {
    $veb.html("index.html")
}

index.html is just a file with <html></html> inside.

What did you expect to see?

No error. Ideally a result struct with the generated html code of the template.

What did you see instead?
