---------------------------------------
Maybe also "tune" hasVariable since internal map could be with default feature

> groovy.lang.Script.getProperty() calls Binding.getProperty() and does
> therfore react on MissingPropertyException. This control flow is an
> antipattern causing unnecessary Throwable.fillInStackTrace() calls which cost
> cpu time. It might be better to check with Binding.hasProperty() first to
> avoid Exception flow.
