* Unnecessary regex modifier. I agree with this inspection which flags
/s modifiers on regexes that don't use a dot.
* Property declared dynamically.
* Unused local variable. But it's acceptable for an unused local
variable to take the return value of a method under test, when it is
being tested for its side-effects. And it's acceptable for an unused
local variable to document unused list expansion elements, or the
nature of array keys in a foreach.
