Subject: Matrix-element extractor -- How to define it

Hi,

I defined and populated a 9x9 matrix (Array of Arrays) of strings, m

I defined an element-extractor:

class Array
	def get(i,j)
		line =self[i-1]
		char = line[j-1]
	end
end

To get the first element of the second row, I used the following,
which worked fine:

m.get(2,1)

I'd like to write merely m(2,1).  How can I do that simply?

Thanks in Advance,
Richard
