Overview

This cop checks for methods invoked via the

operator instead

of the . operator (like FileUtils::rmdir instead of FileUtils.rmdir).

Examples:

# bad
Timeout::timeout(500) { do_something }
FileUtils::rmdir(dir)
Marshal::dump(obj)

# good
Timeout.timeout(500) { do_something }
FileUtils.rmdir(dir)
Marshal.dump(obj)
