Just thinking, in #3859 I mapped matlab variables to `tm_tag_variable_t` so they are displayed in the sidebar but maybe the result is a little too verbose. Especially since it generates a tag for every variable assignment - I just tried it with some random code from github and it displays lots of identical variables in the sidebar, just every time the variable gets assigned.
So shouldn't we rather map it to `tm_tag_undef_t`?
Hum yeah if it's gonna tag every variable assignment in the file regardless of scope, it's probably better to disable indeed, otherwise the more useful tags are likely gonna be hard to find. Maybe `tm_local_var_t` if we want, to still have goto stuff? Not sure if it's really useful though.
