`num as {integer}` cast does not work? about askama HOT 4 OPEN

It's possible we don't support as casts. Maybe 51_i64 is supported? I forget...

Nope, doesn't work either :(

use askama::Template;

#[derive(Template)]
#[template(ext = "txt", source = r#"
    {% let a = 51 %} // works
    {% let a = 51_i64 %} // does not work
"#)]
struct HelloTemplate {}

fn main() {
    let a = 51_i64; // sanity check that it works in normal Rust code
    let hello = HelloTemplate {};
    println!("{}", hello.render().unwrap());
}

Okay, well, if you want to try hacking it in, the code for binary expressions is around here:

https://github.com/djc/askama/blob/main/askama_parser/src/expr.rs#L107

If you can submit a patch with a basic test I'm happy to review it and/or provide more guidance.

In the meantime using i64::from(51) should work.
