[poorna2152]

Description

Consider the following example.
Unused variable warning is given for the category variable. This was reported here and was not fixed in the PR sent for that.

type Doctor record {
    string name;
    string category;    
};

function addDoctor(Doctor doctor, string[] categories) returns error? {
    var {category} = doctor; // also getting an unused variable warning
    if !categories.some(
        existingCategory => existingCategory == category) {
        
    }
}
