code snippet to reproduce:

macro_rules! a_macro {
    () => {}
}

In my color scheme, fat arrows are supposed to be green, and the textmate tokens correctly categorize => as fat arrow here. However, the > part of the arrow token has the semantic token type "angle", even though as far as I'm aware, a > which is part of a => token can never function as an angle bracket, and it certainly does not have this function in this case. As far as I'm aware, this happens for any => which is part of the syntax for a macro invocation or definition.
