What is a "reasonable language"? > Calling it 'multiline' is dumb and confusing, so let's not do this :) ; it > is in fact also called 'singleline' in some sources (which is even dumber). Since there are two different anchors for begin / end of line and begin / end of string a multi line mode which switches anchoring behavior of ^ and $ does not really make sense in Ruby. For me the issue claimed on the web site referenced does not exist. Glancing over the list I wouldn't worry too much. Some information is outdated, some information is completely subjective. There are also "issues" which are common to multiple language. That might be an indication that the criteria are not widely shared.
