Prefer named struct fields

Severity: Info ID: named-struct-fields

Flags struct construction expressions that pass fields positionally instead of by name.

What it does

Reports Struct(a, b, c) style struct construction; suggests Struct({ field1: a, field2: b, field3: c }) instead.

Why is this bad?

Positional struct construction is fragile: adding or reordering fields silently changes the meaning of every existing call site. Named-field construction is self-documenting and resilient to struct changes.

Example

Bad

User memory u = User(addr, 100, true);

Good

User memory u = User({ wallet: addr, balance: 100, active: true });
