Expected Behavior

If the anonymouse function is static, it should also remove the static keyword, as otherwise the changed code containing the $this variable will break.

Just a minor thing. I think removing the static keyword should always be fine in this case, but maybe some deeper analysis is needed? Otherwise the rule should maybe ignore static functions.

Thanks for reporting.
Can you send PR to remove the keyword?
