That is my version for problem solving.  
I want to simplify it

if params[:param]  
paramater = Hash.new  
for value in params[:param].split(/,/)  
if value =~ /(._)=(._)/  
parameter[$1] = $2  
end  
end  
end  
puts parameter.inspect

But… but… neither of you guys’s version gives the same result as  
Jonh’s 🙂

I think this does:

Hash[\*str.scan(/([^,]+)=([^,]+)/).flatten]

We decided he didn’t really want those spaces. We’re always forcing  
our opinions on others. Luckily, David is nice than we are. 😉

I was going to do that too, until I realized that it lost  
fields. 😉 I imagine they aren’t needed though and your way is much  
better.
