Indeed also the ruby style guide recommends to not putting spaces between method names and parenthesis. Definitely I'm going to ask, please, to review the ruby style guide: https://github.com/bbatsov/ruby-style-guide And try to follow its recommendations for this module. I know the msf code isn't strictly compliant with this ruby styling guide. Neither is a requirement for this module. But this module code is hard to read, so I really would like to ask to review it and try to make as compatible as possible with the mentioned ruby style guide.
