Regexp#=~ - Try to cast instance via #to_str if not already a String instance.
Fixes #204. Patches _rubyInspect instead of rubyFullName to ensure the
name can be blank but the inspect/to_s is meaningful.
Kernel#warn should always output regardless of $VERBOSE
warn should only NOT output if $VERBOSE is nil.
Merge pull request #205 from zenspider/master
