Ability to hint proper parameter names for functional interfaces

[TheMode]

I am (re)-using multiple common functional interfaces in my code, and the parameter names sometimes do not properly match the intent. For example DoubleUnaryOperator taking a double generically named operand.

I believe there could be an annotation hinting the IDE into using our own name

// What is currently suggested
Vec.ZERO.withX(operand -> operand * 5);
// With hint
Vec.ZERO.withX(x -> x * 5);

// Similar example using UnaryOperator
// What is currently suggested
itemBuilder.meta(itemMetaBuilder -> itemMetaBuilder);
// With hint
itemBuilder.meta(metaBuilder -> metaBuilder);

The alternative would be creating my own interfaces, which feels a bit unnecessary.
