Error code E0744

Note: this error code is no longer emitted by the compiler.

An unsupported expression was used inside a const context.

Erroneous code example:

const _: i32 = {
    async { 0 }.await

At the moment, .await is forbidden inside a const, static, or const fn.

This may be allowed at some point in the future, but the implementation is not yet complete. See the tracking issue for async in const fn.
