Description

Reproduction

I am certain Swift Java developers know about this limitation, but I don't see any issues mentioning type inference explicitly. As of 5764bc2a1b706056121109dc0ab14fd3d771cbc5 for the following code:

public class Foo {
    public let a = 1
    public let b: Int = 1
}

only the b property is exported; the property a that doesn't spell out the type explicitly is skipped and I also don't see any mentions of this in the logs of jextract.

Research direction

Reproduce the provided Foo example with jextract and inspect how the two properties are handled during Java export. Trace the property-export path and its diagnostics, then verify that the inferred-type property is exported alongside the explicitly typed property.
