08:24 PM Ruby Misc #21367: Remove link to ruby-doc.org from www.ruby-lang.org/en/documentation/

> I couldn't find the precise rationale, but @matz seemed to believe (at least at the time) that code like `d.to_f rescue 0.0` should work even when `d` is nil. This appears to be one of the reasons why `NoMethodError` was made a subclas... p8 (Petrik de Heus)
