Why Remix is telling me to use "pure"?

Question

pragma solidity ^0.6.0;

contract enumTesting{
    enum frenchFriesSize {large, medium, small}
    frenchFriesSize choice;
    frenchFriesSize constant defaultChoice = frenchFriesSize.medium;
    
    
    function setSmall() public {
        choice = frenchFriesSize.small;
    }
    
    function getChoice() public view returns(frenchFriesSize){
        return choice;
    }
    
    function getDefault() public view returns(uint){
        return uint(defaultChoice);
    }
    
}

Remix is sugesting me to change the getDefault function to "pure", but isn't reading the variable "defaultChoice" from outside of the function?

Answer 1

Remix recommends to declare the function as pure because defaultChoice isn't a variable. The compiler does inline constant in the code so they don't use space in storage.
