Make reserved keywords escapeable

[dennisschroeder]

Right now, it is not possible to declare custom types where field names match a keyword.
Example:

    pub type Event {
        Event(type: String)
    }

The compiler will respond with a syntax error because type is a reserved keyword in gleam.
One solution could be to mark those keywords with single quotes 'type', since they have no special meaning in gleam, as far as I know.

What do you think about this?

If the call is no, I would love to have a definite list of all keywords not available for various purposes (like labels or fields) - would that be possible?

Kotlin uses backticks:

fun `fun`() = "Very fun"
fun `this is also a function name`() = "Hello world"

Rust uses a r# prefix:

struct r#for {
    r#while: r#in,
}

Note that Kotlin allows special characters (like whitespace and punctuation) in identifiers, but Rust does not.
