I would add that no highlighting would be applied to this mistyped word as it would not be recognised as a variable or a keyword. This may depend on the way syntax highlighting is handled. A common solution like treesitter would sus out that no variable with the name retunr exists, probably causing the mythical base colour to be applied, heh. That is arguably a big highlight in a colourscheme that rarely uses its base colour.
