Knowing default parameter value

I have a method definition like this:

def m1(a:Int, b:String, c:Val)                                                 
end

m = method(:m1)

Note that Int, String, Val are default values for a, b, c.

Is it possible to get this information from the method object m?

No, this is not possible. It has been discussed numerous times on the ruby-core mailinglist, but it's simply not feasible. What should your proposed method return for something like this:

def m(p: if rand < 0.5 then Time.now else ENV['HOME'] end) end
