What did you do?

Tested out the following sample code:

package main

func main() {
    foo := func(x string) string { return x } 
    foo
    foo("hello")
}

What did you see happen?

The lsp.type.function semantic token is assigned to all references of foo except for foo's declaration.
swappy-20240413_174517

Note the difference in the highlighting. The components that carry the lsp.type.function token will be highlighted in blue.

What did you expect to see?

Better consistency in the assignment of semantic tokens.

Thanks. We're enabling semantic tokens by default in the next minor version of gopls, and will investigate.
