Description

Hi,

Would it be possible to list all keywords in Ruby, from within a running program?

Like RUBY_KEYWORDS or similar?

Reasoning: On IRB someone asked me if "in" is a keyword. I was not sure so I googled
because I could not remember right off the head (I later remembered that "in" must
be because it is used in a "for" loop).

It would be nice if we could ask ruby itself which keywords would be available,
i.e. stored in an array.

http://ruby-doc.org/docs/keywords/1.9/ has a nice description of all keywords
too, which is great.
