LYR-PAR0003

a member name or a compile-time form is incomplete

error · spec 02-grammar

A . or ?. is followed by no member name (or by a number that is no tuple position), or the parts of a compile-time form are missing: the parentheses of comptime if or comptime for in an initializer, the ] of e.[f], the field and = of a with.

Explanation

After . and ?. stands the name of a member, or the position of a tuple element, t.0. The compile-time forms have fixed parts: comptime if (c) a else b, e.[f], p with { x = 1 }.

Write the member's name after the dot, or complete the form.

Wrong

fn main(): void {
    let s = "abc";
    let n = s.;
}

Right

fn main(): void {
    let s = "abc";
    let _ = s.length;
}
